Ancient Aliens s19e19 Episode Script
The Top Ten Mysteries Of The Deep
Sunken continents
said to have once been home
to advanced civilizations.
An ancient shipwreck
containing what might be
evidence of Atlantis.
And unidentified
submersible objects
moving through our oceans.
For more than a decade,
Ancient Aliens
has traveled the globe
to investigate
some of the most
puzzling discoveries
made in the depths
of our oceans.
Now we're exploring
the top ten
mysteries of the deep
that just may hold the proof
that Earth has been visited
by extraterrestrials.
The ocean is the most
mysterious place on Earth.
It covers 70% of our planet,
but less than 10% of it
has been explored.
In fact, we know more
about the surface of Mars
than we do about
the bottom of our own oceans.
But what we have
discovered in the depths
is a treasure trove of evidence
for the ancient
astronaut theory.
Like an incredible
underwater formation
that was found off the coast
of Japan in the 1980s.
Number ten on our countdown
of the top ten mysteries
of the deep:
The Yonaguni Monument.
In the Pacific Ocean,
at the westernmost tip
of the Japanese archipelago,
lies the small
island of Yonaguni.
In 1987, in nearby waters,
dive tour operator
Kihachiro Aratake
made a shocking discovery.
He found a massive complex
of stone formations
that lay hidden a mere 60 feet
beneath the ocean's surface.
It's an absolutely
incredible structure.
It looks like a giant staircase.
There are steps
in the bedrock with terraces.
The symmetry and the regularity
that people see on it
just makes
a astounding impression.
It looks like a huge,
multifaceted pyramid platform
that stretches over a huge area
with all these details
carved into it.
There's areas where monoliths
were said to have been standing.
There's even dolmens,
or large slabs like lintels
covering areas and creating
doorways and other features.
Although some
researchers suggest
that the so-called
Yonaguni Monument
is simply a rock formation,
many experts, including
Japanese archeologist
Masaaki Kimura,
have come to believe
it is an artificial structure
that was built
in the distant past.
There are several reasons why
I think this is not
a natural formation.
A number of tools and
numerous engraved stones
were found at the site.
Because of these things,
there is no doubt to me
that this was made artificially.
There are all these different
cuts that seem to be
of artificial origin
and not of a natural origin
because it's too precise.
Was Yonaguni artificially
altered at a time
when the water levels
of the oceans were lower?
We know that this happened
at some point
during the last ice age,
which was 14,000 years ago.
Could this massive
underwater structure
really be the remnants
of an advanced civilization
that existed here on Earth
more than 10,000 years ago?
And if so, who built it?
The Yonaguni Monument is
particularly interesting
because some of
the reports suggest that
this was built 20,000 years ago.
So the question is
how was it built
with this limited ability
of these people
that were known to have
exist in that time?
If they had
extraterrestrial help,
it would solve a lot of problems
in trying to understand
how a civilization
could mount
such a daunting enterprise
without what we see are
the necessary skills to do so.
Was Yonaguni built
thousands of years ago
with the help of
extraterrestrial beings?
Perhaps clues about
its construction
can be found in the mythology
of Japan's royal family.
It was said in ancient Japan,
that the dragon god lived
at the bottom of the ocean.
His daughter had a daughter,
and her child was Jimmu,
the first emperor of Japan.
To be descended from a dragon
is to be from the divine
dimension of nature,
but also from the stars.
When these underwater structures
of Yonaguni were found,
the Japanese became thrilled.
They believed that evidence
for extraterrestrials
was right there
in southern Japan.
To me, the Yonaguni Monument
presents clear evidence
that an advanced society
existed on Earth
long before our earliest
recorded history.
And, in fact,
numerous ancient cultures
around the world tell similar
stories of lost civilizations,
including one that ended up
submerged beneath the sea.
Number nine on our countdown
of the top ten
mysteries of the deep:
The Lost Continent of Mu.
The Pacific Ocean.
This body of water
is the largest on Earth,
covering more than
63 million square miles.
Curiously, many ancient peoples
living throughout
this vast expanse
share the same story
of a long-lost
sunken civilization
often referred
to as Lemuria, or Mu.
Mu was this huge continent
that supposedly existed
from Hawaii in the north,
down to Easter Island
in the southeast,
right the way across
to Micronesia in the west.
It thrived perhaps
50,000 years ago,
and was sunk beneath the waves,
possibly at the end
of the last ice age.
Among the many legends
expressed by Polynesians
and native Hawaiians,
one is that
the lost continent of Mu
was home to visitors
from the Pleiades.
We have all kind of
connection with the Pleiades,
but we call it,
uh, ka po'e o ka lani,
"the people of the heaven."
The Hawaiians believed
that the Hawaiian Islands
were originally part of Mu,
and the belief
is that the Pleiadeans
were the original
settlers of Mu.
While most mainstream scholars
dismiss the stories of Mu
as being little more
than a fanciful myth,
ancient astronaut theorists
claim that remnants of Mu
can still be found today
in the mysterious
ruins of Nan Madol.
Nan Madol is a huge basalt city
that sits on the edge
of the island of Pohnpei
in Micronesia
in the Pacific Ocean.
It's made up of
hundreds of thousands,
potentially millions,
of these huge basalt columns,
and much of the site
is still submerged in the water,
suggesting it must
have been built
many thousands of years ago.
Some people actually suggested
that maybe Nan Madol
was the last remnant of Mu
that was still above water,
and it was simply indicative
of what had sunk
beneath the waves
from this advanced civilization.
Could it be that
the structures on Nan Madol
are ruins of an ancient
extraterrestrial civilization
known as Mu?
According to Rufino Mauricio,
the Director of the Federal
States of Micronesia
Office of National Archives,
it's a distinct possibility.
Legends of lost civilizations
and sunken cities
can be found in cultures
all around the world.
But one has captured
the public's imagination
more than any other.
And some believe
we may have found
evidence of its existence
in the Bermuda Triangle.
Number eight on our top ten
mysteries of the deep:
Atlantis.
For over 2,000 years,
the lost continent of Atlantis
has sparked the imaginations
of historians and explorers.
The first reference
of Atlantis that we have
is in Plato's dialogues
by Timaeus and Critias.
In the very end of Timaeus,
it talks about
this mythical place
called Atlantis
from where any and all
knowledge of the world came.
And so, some people
have suggested
that the first civilization on
Earth may have been Atlantean.
According to legend,
Atlantis was founded
by the god Poseidon.
He fell in love with
a human woman named Cleito,
and they had five sets of twins.
And these twins went on
to be the founders of Atlantis.
Atlantis is thought to be
a great civilization
of high culture
and technological achievement.
They had robotics at
a very advanced level.
The power of levitation,
which is how
they built
their glorious cities.
They had achieved things
that we still
are not able to do.
According to Plato,
Atlantis was destroyed
in a single night
by a cataclysmic flood,
which some identify
as the Great Flood
described in the Bible.
But where the famous city
was located remains a mystery.
Atlantis was allegedly
this land mass that existed
beyond the Pillars of Hercules,
which is today's
Strait of Gibraltar,
and to this day,
if Atlantis existed,
we have no idea
where exactly Atlantis was.
While most mainstream historians
dismiss the story
of the sunken civilization
of Atlantis as a myth,
ancient astronaut theorists
believe it really existed.
And as evidence, they point
to a remarkable discovery
made off the coast of Cuba.
Canadian explorer
Paulina Zelitsky and her team
are conducting an oceanic
survey off the coast
when they detect
curious formations
more than 2,000 feet underwater.
I was in control room
on board of the ship.
There suddenly appeared
a very large, very dark images
of, uh, perfect
geographical shapes.
They found, when
they were taking images,
some kind of
pyramidical structure
and other structures.
There were circular areas,
there was what appeared to be
some kind of city
built down there.
It was about two square
kilometers in size.
And so, this is something
quite astonishing
if this is, you know, a reality.
And almost certainly,
this dates back
several thousand years,
and arguably even earlier,
and is part of
a lost civilization.
Is it possible
that the underwater ruins
off the coast of Cuba are
the actual remains of Atlantis?
Ancient astronaut
theorists say yes,
and as further evidence,
they point to their location
near the Bermuda Triangle,
a region notorious
for mysterious lights,
strange disappearances
and unexplained phenomena.
It's speculated
that in Atlantis,
they were creating huge pyramids
and energy devices.
The idea is that there is
still one of these pyramids,
and it's active beneath
the Bermuda Triangle
on the ocean floor,
and it's creating
these anomalies
that are sometimes seen there
at the Bermuda Triangle.
If you are a researcher
into Atlantis,
this is exactly
the kind of discovery
that you are looking for.
Some kind of pyramid
that's underwater.
And in fact, this may well be,
really, the evidence
for Atlantis that we need.
Did Atlantis really exist?
Recently, a mysterious
metal alloy was recovered
from the depths of the ocean
that may offer further evidence.
Number seven on our countdown:
Orichalcum.
Sicily. 2015.
Archaeologist Sebastiano Tusa
excavates a shipwreck
less than a mile off the coast,
which has remained undisturbed
for more than 2,600 years.
His team dredges up
an ancient payload
of 39 metal ingots.
Spectrographic analysis
of the recovered alloy
reveals the compound
is unlike anything
ever found in the ancient
or modern world.
The interesting part about this
is the composition
of the ingots that they found.
The metal is 80% copper,
and 20% zinc.
There was other things
found in it,
but that's the majority
of the composition.
What's interesting about this
is that zinc doesn't
naturally occur.
We didn't have zinc until
about a thousand years ago,
and this is 2,600 years old.
How is it possible
that such an advanced alloy
was produced
thousands of years ago,
centuries before man had
the technology to create it?
After conducting an analysis,
scientists believe
the mysterious alloy
is orichalcum,
a metal associated
with the legendary
continent of Atlantis.
According to Plato,
orichalcum was
an orangish gold-type metal
that was used in Atlantis.
It's thought that orichalcum
was some kind of
alloy of copper and gold,
and the walls of Atlantis
were wallpapered,
literally,
with this reddish-gold metal.
According to Plato,
this metal was given
to the people of Atlantis
by the Greek god Cadmus.
The actual discovery
of the orichalcum metal
lends credence
to the idea that Cadmus
did exist at one time,
passing this knowledge
to humanity.
And Atlantis could be
an actual physical location,
possibly harnessing and
utilizing other advanced metals.
The reason why this ties in to
the ancient astronaut theory
is based on an idea
that the ancient gods of Greece
were visiting extraterrestrials.
Could this mysterious metal,
found deep beneath
the ocean's surface,
be proof that humans
lived side by side
with otherworldly beings
thousands of years ago?
Ancient astronaut
theorists say yes,
and suggest that
further evidence
of extraterrestrial contact
can be found submerged
in the waters
off the coast of India.
India is a treasure trove
for the ancient
astronaut theory.
Its mythology is chock-full
of stories of flying chariots
and god-like beings
descending from the sky.
And every so often,
the ocean offers us evidence
that these stories
could be true.
At number six on our list
of the top ten mysteries
of the deep:
The Lost Pagodas
of Mahabalipuram.
Mahabalipuram, India.
On December 26, 2004,
a powerful tsunami
caused the water levels
in the city's harbor to drop.
As the waters receded,
residents noticed
something astonishing
emerging from the sea:
the ruins of several
ancient buildings.
The ocean receded
about 500 or so meters,
and people that were there,
they said they saw walls,
they saw structures
that they'd never seen before
'cause now the water was gone.
For the more than
one billion Hindus
around the world,
the discovery of
these underwater ruins
was remarkable because
they may provide evidence
that a sensational story
contained in ancient sacred
texts called the Puranas
is not mythological
but historical.
According to the story,
thousands of years ago,
seven pagodas stood
at Mahabalipuram,
but six of them became
submerged beneath the sea
after the city
was attacked by a god
who came down from the sky.
The legend at Mahabalipuram
says that the god Indra
became jealous
of the special treatment of the
other gods depicted at the site.
And that he then sent
a flood against the city.
Hindu mythology
really reads like
the wildest
science fiction of today.
It's filled with
all kinds of magic stones,
flying spaceships.
In fact, ancient India,
their entire pantheon
of gods is based
exclusively on a cosmic origin,
that they arrived
from deep space.
For centuries,
many Hindus believed
that the Shore Temple
at Mahabalipuram
represented the one surviving
pagoda from Indra's attack.
Could the structures
that were revealed
by the receding
ocean levels in 2004
be the remnants
of the other six pagodas,
proving that
the incredible story is true?
At Mahabalipuram, you have
evidence that the legends
are really correct
about this place.
That it's far more ancient
than archeologists assumed.
And it would seem
to be an indication
that this was a real event,
one that perhaps
included extraterrestrials.
If you leave Mahabalipuram
and travel
1,000 miles northwest,
you will find
another mysterious site
off the coast of India.
20 feet beneath the waves
are the ruins of an ancient city
that some believe was the home
of an extraterrestrial being.
Number five on our list:
The Sunken City of Dwarka.
Dwarka, northwest India.
April 1983.
Marine archeologist Dr. S.R. Rao
begins a seven-year
underwater exploration
just off the coast
of this ancient fishing town,
and what he finds is stunning.
Submerged 20 feet beneath
the surface of the ocean,
he finds sandstone walls,
cobblestone streets,
and further evidence
of a prosperous ancient city
that sank into the sea.
At Dwarka, what has been
found so far under the ocean
is incredibly tantalizing.
For instance,
there's this huge wall,
estimated about 580 meters long.
Pottery has been found,
anchors have been found,
so this seems to have been
a maritime city.
The remains that have been
discovered beneath the waters
have been radiocarbon dated
to at least 9,500 years.
So, this was
many thousands of years
older than that of Sumeria,
Egypt and China.
So, what exactly was going on
in India at this time?
For centuries,
the modern-day city of Dwarka
was thought by many Hindus
to be the Dwarka
described in the Mahabharata
as the ancient kingdom
of the god Krishna.
According to the text,
during the Kurukshetra war,
a rival to Krishna, Lord Salva,
attacked Dwarka
from a flying chariot.
He actually,
uh, flew over Dwarka,
using his chariot,
and he started bombarding
the city of Dwarka,
throwing down
all kinds of weapons.
Shortly after the great war,
Krishna is killed.
And the city,
this magnificent city
built on land that
came out of the sea,
sank back into the ocean again.
It only existed during the time
that Krishna lived there.
Is it possible
that the pre-Vedic
cultures of India
really did have high technology?
And I think, from
the ancient accounts
and what's now been
discovered at Dwarka,
the answer has to be yes.
The discoveries at
Dwarka and Mahabalipuram
provide sensational evidence
that ancient Hindu stories
of advanced technology
are not works of fiction.
And there is yet another
incredible underwater structure
located between
India and Sri Lanka
that may offer further proof.
Number four on our list:
Rama's Bridge.
Just off the southeastern
tip of India lies Sri Lanka.
This island nation has been
an important trading hub
for thousands of years,
but it is nearly impossible
for ships to pass between
Sri Lanka and India
due to a more than 30-mile-long
underwater barrier
that links the two landmasses.
If you look at satellite
imagery, you can see
that there seems to be some
sort of a connector, a road.
This is referred to
as Rama's Bridge.
The mainstream viewpoint
is that Rama's Bridge
is a chain of natural
limestone shoals.
But millions of Hindus
believe the barrier is,
in fact, an ancient bridge,
one that was built by the god
for whom it is named.
Rama is a major Hindu deity,
considered by some
to be the supreme being.
According to the ancient
Sanskrit text the Ramayana,
Rama's wife was kidnapped and
taken to the kingdom of Lanka.
To rescue her, Rama used
magical construction techniques
to build a bridge to Lanka.
Some of the interesting details
of the building of Rama's Bridge
is that they were writing
Rama's name on these stones
and that would magically
levitate the stones.
And some of these
were very big stones, too.
According to the mythology,
you know, Rama lived
around 6,000 years ago,
and there is interesting fact
that some geologists
carbon-date the material
on the bottom
approximately dating
around the same time.
So that kind of corroborates
whether or not
this story is connected
to the mythology
because the age of Rama
is around that period.
In 2018, government
officials in India
voted against plans
to cut a shipping lane
through the middle
of the barrier,
showing their support
for the notion
that the underwater structure
known as Rama's Bridge
was, in fact,
built by the Hindu deity.
Rama's Bridge
to Sri Lanka is real.
And you have to ask
yourself, was it built
artificially by levitating
stones and putting them there?
That's what
the Ramayana tells us.
Some of the mysteries
we've investigated
on Ancient Aliens
are so baffling,
we can only guess at
what might explain them.
And perhaps one of
the most mystifying
lies on the islands of Malta.
Number three on our countdown
of the top ten
mysteries of the deep:
The Malta Cart Ruts.
In the middle of
the Mediterranean Sea,
just south of Sicily,
lies the Republic of Malta.
This tiny island nation
boasts some of the most
impressive megalithic structures
on the planet.
And crisscrossing the islands
is something even
more mysterious:
a complex network of grooves
carved into the bedrock
known simply as the "cart ruts."
Something that Malta
is very well known for
archaeologically,
besides the megalithic temples,
are the cart ruts.
These are ruts literally
in the limestone rock.
If you have grooves
that were created by some sort
of a transportation device,
well, it had to have been
pulled by something,
so where are the footprints?
There are no footprints.
How and why the cart ruts
were formed remains a mystery,
but their existence
poses a profound possibility,
because some believe
they may reveal that there
was human activity on Malta
many thousands of years before
what has been suggested
by mainstream archaeology.
We have cart ruts
that go into
the Mediterranean Sea.
And then they also
come out on the other side.
How is this possible?
Some of the cart ruts
that extend from dry land
down into the sea
have reportedly been found
at depths
of as much as 140 feet.
This presents a critical clue
as to just how long ago
they must have been created.
I suspect that some of these
cart ruts are really ancient,
and when I say "really ancient,"
that is going back
to before the end
of the last ice age.
So, approximately,
uh, 12,000 years or so,
the ice age ended, we know.
Some of these cart ruts
going into the water,
that would've been dry land
when sea levels were much lower.
If you propose the idea
that 12,000 years ago,
which is a fact, the worldwide
water levels were lower,
then all of a sudden,
these cart ruts
that go into the Mediterranean
Sea make sense.
The fact that
these cart ruts exist,
to me, illustrates that
an advanced civilization
must have existed at that time.
If the cart ruts are
more than 12,000 years old,
as some researchers suggest,
who would have been
around to create them?
It's a question
that continues to baffle
mainstream archaeologists.
But according
to local traditions,
the megalithic
structures on Malta
were built by
a race of giant beings
who came to Earth
from the stars.
We have to be open
to the possibility
that whoever built these
were not, in fact, human beings,
but were perhaps
a separate race,
and their existence
and even their origins,
is completely
shrouded in mystery.
Are the so-called "cart ruts,"
that not only crisscross Malta
but extend deep into
the Mediterranean Sea,
evidence of advanced,
otherworldly visitors?
For ancient astronaut theorists,
the answer is a resounding yes.
And they suggest
that the waters of our oceans
not only contain evidence
of extraterrestrial visitation
in the distant past,
but they are the location
of encounters
that are happening
to this very day.
Most people assume that UFOs
are only seen up in the sky.
But what if I told you
that some of the most
widely reported sightings
involve mysterious craft
flying in and out of our oceans?
Number two on our countdown
of the top ten mysteries
of the deep:
Unidentified
Submersible Objects.
Hitachi Province, Japan.
Local fishermen are astonished
when a mysterious metal craft
washes ashore that is unlike
anything they have ever seen.
This craft was likened
to the shape of
a Japanese incense burner.
It is almost literally
a flying disk, a flying saucer.
On the outside of this craft
were multiple
small metal plates,
not too dissimilar
to heat-resistant tiles
that you'd find, say,
on a space shuttle.
A hatch opened,
and a young woman
came out of the craft
dressed in clothes that
had never been seen before,
and speaking a language
that nobody understood
in the slightest.
The story of the strange craft
appears in three
different Japanese texts.
Even today, modern historians
struggle to understand
what this means.
Another famous incident
involving a strange craft
emerging from underwater
occurred in
Yunnan Province, China,
on October 24, 1991.
A local man was fishing
on Fuxian Lake
on a clear and tranquil day
when a large disc suddenly
flew out of the water.
This strange craft
actually emerged from
the waters of the lake.
He described it
as a shining disc.
This UFO was so close
and so powerful
that it actually
tossed the boat around.
And then, rapidly, this craft
just disappeared
up into the sky.
Navy personnel
aboard the USS Omaha
capture footage
of a mysterious round object
flying into the ocean.
Night footage
actually shows a craft
that is spherical and
it's flying through the air
and then suddenly
it flies into the water
without making a splash.
Japan. China.
San Diego.
These are just three
out of hundreds of reports
of what are known as "USOs."
A USO is an "unidentified
submerged object."
It's the same thing as a UFO,
except this one's in the water,
and a UFO is a flying object.
You see them off
the coast of California,
you see them a lot
in the Gulf of Mexico.
Spend some time on
the Florida Gulf Coast,
you will see a USO.
These objects are flying along,
uh, through the atmosphere,
and then suddenly,
they go into the ocean.
No splash, no wake, nothing.
They just go
right into the water
and then come out of the water
in many cases, and fly away.
Now, one such never
came out of the water,
and a submarine was actually
dispatched to look for a craft
that may have crashed,
but never found anything.
The stresses and strains
by flying through
the atmosphere,
in outer space and then
plunging into the oceans
would be enough to rupture
any of our known aircraft.
For ancient astronaut theorists,
perhaps the most
compelling story
of an extraterrestrial
presence in Earth's oceans
can be found in an account
from 1492,
recorded by
Christopher Columbus.
There's a famous story
about Christopher Columbus
and he wrote this
in his journals
that as he was moving
west across the Atlantic,
towards the Caribbean,
in his first voyage,
he saw a light out
in the ocean to the west,
hovering over the water.
And this light then
descended into the water.
So, he's perhaps one of
the first witnesses to describe
a trans-medium craft like this,
which could hover,
uh, above the water
and then disappear
into it like a submarine.
Stories of undersea objects,
glowing objects
that fly out of the water,
have been around
for well over
thousands of years.
Are these machines
that the extraterrestrials
have under the water?
There is only one mystery
left on our countdown,
and you don't want to miss it
because what was discovered
just may be evidence of
an underwater alien base.
On Ancient Aliens,
we've investigated
the ocean's biggest mysteries
for evidence of extraterrestrial
contact in the distant past.
But recent satellite images
may suggest that
otherworldly beings
are inhabiting our oceans today.
Number one on our list
of the top ten
mysteries of the deep:
Underwater Alien Bases.
With almost
200 miles of coastline,
this picturesque region
is famous for its beaches,
surfing and abundant sea life.
It is also a hotspot
for sightings of mysterious
lights in the water.
Folks have seen lights
in the water outside Point Dume
off the Malibu coast.
There is this
very strange 911 call
from an observer
near Point Dume,
saying he saw a light
coming out of the water
and calling it into
the sheriff's station.
One theory about this
trans-medium travel
and these USOs
is that what we're seeing
is evidence of underwater bases.
They're operating here,
but under the oceans,
right under our noses.
While the idea of
underwater alien bases
in Earth's oceans may
sound like science fiction,
in 2014, satellite imagery
revealed a very curious
formation on the seabed
six miles off
the coast of Malibu.
The satellite photos
show what seems to be
an oval, flat-topped structure
that's got legs coming
down that are holding it up.
It's about
2,000 feet underwater.
A lot of people got
very excited by this discovery.
It's really quite striking,
and it really does
look artificial.
And it makes you
wonder, is this,
as some believe,
an extraterrestrial base?
Is there a connection
between the strange lights
seen in the waters off
the coast of Southern California
and the mysterious
undersea structure
captured in the satellite image?
For some scientists,
it's a distinct possibility.
If all these objects
are buzzing our aircraft,
they must have
a base of operations.
But you see, if they have
a base of operations
that's easily detected
by us humans,
it would sort of defeat
the purpose of observing us.
So, perhaps there's
an underwater base
that is away from
prying eyes of humans
so that we don't
interfere with their plans.
That cannot be ruled out.
While the formation
discovered deep in the ocean
off the coast of Malibu
is highly unusual,
it is not entirely unique.
Across the globe,
mysterious anomalies
have been detected on the seabed
that some suggest are
underwater alien structures.
The under ocean
geological survey
determined that there were
dome-like structures
between Cuba and
the coast of Florida.
Was that a USO base?
Because underwater,
underneath our oceans,
best place,
the very best place
to conceal yourself.
Absolutely anything
could be hiding within
the oceans themself.
And the depths of them
could hide vehicles,
could even hide bases,
uh, for hundreds,
if not thousands of years.
We would not be aware
of their presence.
The oceans have everything
that the crew of a ship
would need to survive.
It's got plants and animals
that can be harvested for food.
There's minerals and salt
that can be taken
from the water.
You can even
separate the hydrogen
from the oxygen in the water
to create fuels
and-and air to breathe.
Everything that is
necessary for life
can be found in the oceans,
and it may be that
if extraterrestrials
are in our oceans,
they're not just hiding there,
this may be
their preferred environment.
The idea that alien
bases might be hidden
on the ocean floor
is incredibly thrilling.
But while much of
the ocean's depths
remain impossible to explore,
ancient astronaut
theorists believe
that the deeper we go,
the closer
we'll get to the truth
about mankind's
extraterrestrial past.
said to have once been home
to advanced civilizations.
An ancient shipwreck
containing what might be
evidence of Atlantis.
And unidentified
submersible objects
moving through our oceans.
For more than a decade,
Ancient Aliens
has traveled the globe
to investigate
some of the most
puzzling discoveries
made in the depths
of our oceans.
Now we're exploring
the top ten
mysteries of the deep
that just may hold the proof
that Earth has been visited
by extraterrestrials.
The ocean is the most
mysterious place on Earth.
It covers 70% of our planet,
but less than 10% of it
has been explored.
In fact, we know more
about the surface of Mars
than we do about
the bottom of our own oceans.
But what we have
discovered in the depths
is a treasure trove of evidence
for the ancient
astronaut theory.
Like an incredible
underwater formation
that was found off the coast
of Japan in the 1980s.
Number ten on our countdown
of the top ten mysteries
of the deep:
The Yonaguni Monument.
In the Pacific Ocean,
at the westernmost tip
of the Japanese archipelago,
lies the small
island of Yonaguni.
In 1987, in nearby waters,
dive tour operator
Kihachiro Aratake
made a shocking discovery.
He found a massive complex
of stone formations
that lay hidden a mere 60 feet
beneath the ocean's surface.
It's an absolutely
incredible structure.
It looks like a giant staircase.
There are steps
in the bedrock with terraces.
The symmetry and the regularity
that people see on it
just makes
a astounding impression.
It looks like a huge,
multifaceted pyramid platform
that stretches over a huge area
with all these details
carved into it.
There's areas where monoliths
were said to have been standing.
There's even dolmens,
or large slabs like lintels
covering areas and creating
doorways and other features.
Although some
researchers suggest
that the so-called
Yonaguni Monument
is simply a rock formation,
many experts, including
Japanese archeologist
Masaaki Kimura,
have come to believe
it is an artificial structure
that was built
in the distant past.
There are several reasons why
I think this is not
a natural formation.
A number of tools and
numerous engraved stones
were found at the site.
Because of these things,
there is no doubt to me
that this was made artificially.
There are all these different
cuts that seem to be
of artificial origin
and not of a natural origin
because it's too precise.
Was Yonaguni artificially
altered at a time
when the water levels
of the oceans were lower?
We know that this happened
at some point
during the last ice age,
which was 14,000 years ago.
Could this massive
underwater structure
really be the remnants
of an advanced civilization
that existed here on Earth
more than 10,000 years ago?
And if so, who built it?
The Yonaguni Monument is
particularly interesting
because some of
the reports suggest that
this was built 20,000 years ago.
So the question is
how was it built
with this limited ability
of these people
that were known to have
exist in that time?
If they had
extraterrestrial help,
it would solve a lot of problems
in trying to understand
how a civilization
could mount
such a daunting enterprise
without what we see are
the necessary skills to do so.
Was Yonaguni built
thousands of years ago
with the help of
extraterrestrial beings?
Perhaps clues about
its construction
can be found in the mythology
of Japan's royal family.
It was said in ancient Japan,
that the dragon god lived
at the bottom of the ocean.
His daughter had a daughter,
and her child was Jimmu,
the first emperor of Japan.
To be descended from a dragon
is to be from the divine
dimension of nature,
but also from the stars.
When these underwater structures
of Yonaguni were found,
the Japanese became thrilled.
They believed that evidence
for extraterrestrials
was right there
in southern Japan.
To me, the Yonaguni Monument
presents clear evidence
that an advanced society
existed on Earth
long before our earliest
recorded history.
And, in fact,
numerous ancient cultures
around the world tell similar
stories of lost civilizations,
including one that ended up
submerged beneath the sea.
Number nine on our countdown
of the top ten
mysteries of the deep:
The Lost Continent of Mu.
The Pacific Ocean.
This body of water
is the largest on Earth,
covering more than
63 million square miles.
Curiously, many ancient peoples
living throughout
this vast expanse
share the same story
of a long-lost
sunken civilization
often referred
to as Lemuria, or Mu.
Mu was this huge continent
that supposedly existed
from Hawaii in the north,
down to Easter Island
in the southeast,
right the way across
to Micronesia in the west.
It thrived perhaps
50,000 years ago,
and was sunk beneath the waves,
possibly at the end
of the last ice age.
Among the many legends
expressed by Polynesians
and native Hawaiians,
one is that
the lost continent of Mu
was home to visitors
from the Pleiades.
We have all kind of
connection with the Pleiades,
but we call it,
uh, ka po'e o ka lani,
"the people of the heaven."
The Hawaiians believed
that the Hawaiian Islands
were originally part of Mu,
and the belief
is that the Pleiadeans
were the original
settlers of Mu.
While most mainstream scholars
dismiss the stories of Mu
as being little more
than a fanciful myth,
ancient astronaut theorists
claim that remnants of Mu
can still be found today
in the mysterious
ruins of Nan Madol.
Nan Madol is a huge basalt city
that sits on the edge
of the island of Pohnpei
in Micronesia
in the Pacific Ocean.
It's made up of
hundreds of thousands,
potentially millions,
of these huge basalt columns,
and much of the site
is still submerged in the water,
suggesting it must
have been built
many thousands of years ago.
Some people actually suggested
that maybe Nan Madol
was the last remnant of Mu
that was still above water,
and it was simply indicative
of what had sunk
beneath the waves
from this advanced civilization.
Could it be that
the structures on Nan Madol
are ruins of an ancient
extraterrestrial civilization
known as Mu?
According to Rufino Mauricio,
the Director of the Federal
States of Micronesia
Office of National Archives,
it's a distinct possibility.
Legends of lost civilizations
and sunken cities
can be found in cultures
all around the world.
But one has captured
the public's imagination
more than any other.
And some believe
we may have found
evidence of its existence
in the Bermuda Triangle.
Number eight on our top ten
mysteries of the deep:
Atlantis.
For over 2,000 years,
the lost continent of Atlantis
has sparked the imaginations
of historians and explorers.
The first reference
of Atlantis that we have
is in Plato's dialogues
by Timaeus and Critias.
In the very end of Timaeus,
it talks about
this mythical place
called Atlantis
from where any and all
knowledge of the world came.
And so, some people
have suggested
that the first civilization on
Earth may have been Atlantean.
According to legend,
Atlantis was founded
by the god Poseidon.
He fell in love with
a human woman named Cleito,
and they had five sets of twins.
And these twins went on
to be the founders of Atlantis.
Atlantis is thought to be
a great civilization
of high culture
and technological achievement.
They had robotics at
a very advanced level.
The power of levitation,
which is how
they built
their glorious cities.
They had achieved things
that we still
are not able to do.
According to Plato,
Atlantis was destroyed
in a single night
by a cataclysmic flood,
which some identify
as the Great Flood
described in the Bible.
But where the famous city
was located remains a mystery.
Atlantis was allegedly
this land mass that existed
beyond the Pillars of Hercules,
which is today's
Strait of Gibraltar,
and to this day,
if Atlantis existed,
we have no idea
where exactly Atlantis was.
While most mainstream historians
dismiss the story
of the sunken civilization
of Atlantis as a myth,
ancient astronaut theorists
believe it really existed.
And as evidence, they point
to a remarkable discovery
made off the coast of Cuba.
Canadian explorer
Paulina Zelitsky and her team
are conducting an oceanic
survey off the coast
when they detect
curious formations
more than 2,000 feet underwater.
I was in control room
on board of the ship.
There suddenly appeared
a very large, very dark images
of, uh, perfect
geographical shapes.
They found, when
they were taking images,
some kind of
pyramidical structure
and other structures.
There were circular areas,
there was what appeared to be
some kind of city
built down there.
It was about two square
kilometers in size.
And so, this is something
quite astonishing
if this is, you know, a reality.
And almost certainly,
this dates back
several thousand years,
and arguably even earlier,
and is part of
a lost civilization.
Is it possible
that the underwater ruins
off the coast of Cuba are
the actual remains of Atlantis?
Ancient astronaut
theorists say yes,
and as further evidence,
they point to their location
near the Bermuda Triangle,
a region notorious
for mysterious lights,
strange disappearances
and unexplained phenomena.
It's speculated
that in Atlantis,
they were creating huge pyramids
and energy devices.
The idea is that there is
still one of these pyramids,
and it's active beneath
the Bermuda Triangle
on the ocean floor,
and it's creating
these anomalies
that are sometimes seen there
at the Bermuda Triangle.
If you are a researcher
into Atlantis,
this is exactly
the kind of discovery
that you are looking for.
Some kind of pyramid
that's underwater.
And in fact, this may well be,
really, the evidence
for Atlantis that we need.
Did Atlantis really exist?
Recently, a mysterious
metal alloy was recovered
from the depths of the ocean
that may offer further evidence.
Number seven on our countdown:
Orichalcum.
Sicily. 2015.
Archaeologist Sebastiano Tusa
excavates a shipwreck
less than a mile off the coast,
which has remained undisturbed
for more than 2,600 years.
His team dredges up
an ancient payload
of 39 metal ingots.
Spectrographic analysis
of the recovered alloy
reveals the compound
is unlike anything
ever found in the ancient
or modern world.
The interesting part about this
is the composition
of the ingots that they found.
The metal is 80% copper,
and 20% zinc.
There was other things
found in it,
but that's the majority
of the composition.
What's interesting about this
is that zinc doesn't
naturally occur.
We didn't have zinc until
about a thousand years ago,
and this is 2,600 years old.
How is it possible
that such an advanced alloy
was produced
thousands of years ago,
centuries before man had
the technology to create it?
After conducting an analysis,
scientists believe
the mysterious alloy
is orichalcum,
a metal associated
with the legendary
continent of Atlantis.
According to Plato,
orichalcum was
an orangish gold-type metal
that was used in Atlantis.
It's thought that orichalcum
was some kind of
alloy of copper and gold,
and the walls of Atlantis
were wallpapered,
literally,
with this reddish-gold metal.
According to Plato,
this metal was given
to the people of Atlantis
by the Greek god Cadmus.
The actual discovery
of the orichalcum metal
lends credence
to the idea that Cadmus
did exist at one time,
passing this knowledge
to humanity.
And Atlantis could be
an actual physical location,
possibly harnessing and
utilizing other advanced metals.
The reason why this ties in to
the ancient astronaut theory
is based on an idea
that the ancient gods of Greece
were visiting extraterrestrials.
Could this mysterious metal,
found deep beneath
the ocean's surface,
be proof that humans
lived side by side
with otherworldly beings
thousands of years ago?
Ancient astronaut
theorists say yes,
and suggest that
further evidence
of extraterrestrial contact
can be found submerged
in the waters
off the coast of India.
India is a treasure trove
for the ancient
astronaut theory.
Its mythology is chock-full
of stories of flying chariots
and god-like beings
descending from the sky.
And every so often,
the ocean offers us evidence
that these stories
could be true.
At number six on our list
of the top ten mysteries
of the deep:
The Lost Pagodas
of Mahabalipuram.
Mahabalipuram, India.
On December 26, 2004,
a powerful tsunami
caused the water levels
in the city's harbor to drop.
As the waters receded,
residents noticed
something astonishing
emerging from the sea:
the ruins of several
ancient buildings.
The ocean receded
about 500 or so meters,
and people that were there,
they said they saw walls,
they saw structures
that they'd never seen before
'cause now the water was gone.
For the more than
one billion Hindus
around the world,
the discovery of
these underwater ruins
was remarkable because
they may provide evidence
that a sensational story
contained in ancient sacred
texts called the Puranas
is not mythological
but historical.
According to the story,
thousands of years ago,
seven pagodas stood
at Mahabalipuram,
but six of them became
submerged beneath the sea
after the city
was attacked by a god
who came down from the sky.
The legend at Mahabalipuram
says that the god Indra
became jealous
of the special treatment of the
other gods depicted at the site.
And that he then sent
a flood against the city.
Hindu mythology
really reads like
the wildest
science fiction of today.
It's filled with
all kinds of magic stones,
flying spaceships.
In fact, ancient India,
their entire pantheon
of gods is based
exclusively on a cosmic origin,
that they arrived
from deep space.
For centuries,
many Hindus believed
that the Shore Temple
at Mahabalipuram
represented the one surviving
pagoda from Indra's attack.
Could the structures
that were revealed
by the receding
ocean levels in 2004
be the remnants
of the other six pagodas,
proving that
the incredible story is true?
At Mahabalipuram, you have
evidence that the legends
are really correct
about this place.
That it's far more ancient
than archeologists assumed.
And it would seem
to be an indication
that this was a real event,
one that perhaps
included extraterrestrials.
If you leave Mahabalipuram
and travel
1,000 miles northwest,
you will find
another mysterious site
off the coast of India.
20 feet beneath the waves
are the ruins of an ancient city
that some believe was the home
of an extraterrestrial being.
Number five on our list:
The Sunken City of Dwarka.
Dwarka, northwest India.
April 1983.
Marine archeologist Dr. S.R. Rao
begins a seven-year
underwater exploration
just off the coast
of this ancient fishing town,
and what he finds is stunning.
Submerged 20 feet beneath
the surface of the ocean,
he finds sandstone walls,
cobblestone streets,
and further evidence
of a prosperous ancient city
that sank into the sea.
At Dwarka, what has been
found so far under the ocean
is incredibly tantalizing.
For instance,
there's this huge wall,
estimated about 580 meters long.
Pottery has been found,
anchors have been found,
so this seems to have been
a maritime city.
The remains that have been
discovered beneath the waters
have been radiocarbon dated
to at least 9,500 years.
So, this was
many thousands of years
older than that of Sumeria,
Egypt and China.
So, what exactly was going on
in India at this time?
For centuries,
the modern-day city of Dwarka
was thought by many Hindus
to be the Dwarka
described in the Mahabharata
as the ancient kingdom
of the god Krishna.
According to the text,
during the Kurukshetra war,
a rival to Krishna, Lord Salva,
attacked Dwarka
from a flying chariot.
He actually,
uh, flew over Dwarka,
using his chariot,
and he started bombarding
the city of Dwarka,
throwing down
all kinds of weapons.
Shortly after the great war,
Krishna is killed.
And the city,
this magnificent city
built on land that
came out of the sea,
sank back into the ocean again.
It only existed during the time
that Krishna lived there.
Is it possible
that the pre-Vedic
cultures of India
really did have high technology?
And I think, from
the ancient accounts
and what's now been
discovered at Dwarka,
the answer has to be yes.
The discoveries at
Dwarka and Mahabalipuram
provide sensational evidence
that ancient Hindu stories
of advanced technology
are not works of fiction.
And there is yet another
incredible underwater structure
located between
India and Sri Lanka
that may offer further proof.
Number four on our list:
Rama's Bridge.
Just off the southeastern
tip of India lies Sri Lanka.
This island nation has been
an important trading hub
for thousands of years,
but it is nearly impossible
for ships to pass between
Sri Lanka and India
due to a more than 30-mile-long
underwater barrier
that links the two landmasses.
If you look at satellite
imagery, you can see
that there seems to be some
sort of a connector, a road.
This is referred to
as Rama's Bridge.
The mainstream viewpoint
is that Rama's Bridge
is a chain of natural
limestone shoals.
But millions of Hindus
believe the barrier is,
in fact, an ancient bridge,
one that was built by the god
for whom it is named.
Rama is a major Hindu deity,
considered by some
to be the supreme being.
According to the ancient
Sanskrit text the Ramayana,
Rama's wife was kidnapped and
taken to the kingdom of Lanka.
To rescue her, Rama used
magical construction techniques
to build a bridge to Lanka.
Some of the interesting details
of the building of Rama's Bridge
is that they were writing
Rama's name on these stones
and that would magically
levitate the stones.
And some of these
were very big stones, too.
According to the mythology,
you know, Rama lived
around 6,000 years ago,
and there is interesting fact
that some geologists
carbon-date the material
on the bottom
approximately dating
around the same time.
So that kind of corroborates
whether or not
this story is connected
to the mythology
because the age of Rama
is around that period.
In 2018, government
officials in India
voted against plans
to cut a shipping lane
through the middle
of the barrier,
showing their support
for the notion
that the underwater structure
known as Rama's Bridge
was, in fact,
built by the Hindu deity.
Rama's Bridge
to Sri Lanka is real.
And you have to ask
yourself, was it built
artificially by levitating
stones and putting them there?
That's what
the Ramayana tells us.
Some of the mysteries
we've investigated
on Ancient Aliens
are so baffling,
we can only guess at
what might explain them.
And perhaps one of
the most mystifying
lies on the islands of Malta.
Number three on our countdown
of the top ten
mysteries of the deep:
The Malta Cart Ruts.
In the middle of
the Mediterranean Sea,
just south of Sicily,
lies the Republic of Malta.
This tiny island nation
boasts some of the most
impressive megalithic structures
on the planet.
And crisscrossing the islands
is something even
more mysterious:
a complex network of grooves
carved into the bedrock
known simply as the "cart ruts."
Something that Malta
is very well known for
archaeologically,
besides the megalithic temples,
are the cart ruts.
These are ruts literally
in the limestone rock.
If you have grooves
that were created by some sort
of a transportation device,
well, it had to have been
pulled by something,
so where are the footprints?
There are no footprints.
How and why the cart ruts
were formed remains a mystery,
but their existence
poses a profound possibility,
because some believe
they may reveal that there
was human activity on Malta
many thousands of years before
what has been suggested
by mainstream archaeology.
We have cart ruts
that go into
the Mediterranean Sea.
And then they also
come out on the other side.
How is this possible?
Some of the cart ruts
that extend from dry land
down into the sea
have reportedly been found
at depths
of as much as 140 feet.
This presents a critical clue
as to just how long ago
they must have been created.
I suspect that some of these
cart ruts are really ancient,
and when I say "really ancient,"
that is going back
to before the end
of the last ice age.
So, approximately,
uh, 12,000 years or so,
the ice age ended, we know.
Some of these cart ruts
going into the water,
that would've been dry land
when sea levels were much lower.
If you propose the idea
that 12,000 years ago,
which is a fact, the worldwide
water levels were lower,
then all of a sudden,
these cart ruts
that go into the Mediterranean
Sea make sense.
The fact that
these cart ruts exist,
to me, illustrates that
an advanced civilization
must have existed at that time.
If the cart ruts are
more than 12,000 years old,
as some researchers suggest,
who would have been
around to create them?
It's a question
that continues to baffle
mainstream archaeologists.
But according
to local traditions,
the megalithic
structures on Malta
were built by
a race of giant beings
who came to Earth
from the stars.
We have to be open
to the possibility
that whoever built these
were not, in fact, human beings,
but were perhaps
a separate race,
and their existence
and even their origins,
is completely
shrouded in mystery.
Are the so-called "cart ruts,"
that not only crisscross Malta
but extend deep into
the Mediterranean Sea,
evidence of advanced,
otherworldly visitors?
For ancient astronaut theorists,
the answer is a resounding yes.
And they suggest
that the waters of our oceans
not only contain evidence
of extraterrestrial visitation
in the distant past,
but they are the location
of encounters
that are happening
to this very day.
Most people assume that UFOs
are only seen up in the sky.
But what if I told you
that some of the most
widely reported sightings
involve mysterious craft
flying in and out of our oceans?
Number two on our countdown
of the top ten mysteries
of the deep:
Unidentified
Submersible Objects.
Hitachi Province, Japan.
Local fishermen are astonished
when a mysterious metal craft
washes ashore that is unlike
anything they have ever seen.
This craft was likened
to the shape of
a Japanese incense burner.
It is almost literally
a flying disk, a flying saucer.
On the outside of this craft
were multiple
small metal plates,
not too dissimilar
to heat-resistant tiles
that you'd find, say,
on a space shuttle.
A hatch opened,
and a young woman
came out of the craft
dressed in clothes that
had never been seen before,
and speaking a language
that nobody understood
in the slightest.
The story of the strange craft
appears in three
different Japanese texts.
Even today, modern historians
struggle to understand
what this means.
Another famous incident
involving a strange craft
emerging from underwater
occurred in
Yunnan Province, China,
on October 24, 1991.
A local man was fishing
on Fuxian Lake
on a clear and tranquil day
when a large disc suddenly
flew out of the water.
This strange craft
actually emerged from
the waters of the lake.
He described it
as a shining disc.
This UFO was so close
and so powerful
that it actually
tossed the boat around.
And then, rapidly, this craft
just disappeared
up into the sky.
Navy personnel
aboard the USS Omaha
capture footage
of a mysterious round object
flying into the ocean.
Night footage
actually shows a craft
that is spherical and
it's flying through the air
and then suddenly
it flies into the water
without making a splash.
Japan. China.
San Diego.
These are just three
out of hundreds of reports
of what are known as "USOs."
A USO is an "unidentified
submerged object."
It's the same thing as a UFO,
except this one's in the water,
and a UFO is a flying object.
You see them off
the coast of California,
you see them a lot
in the Gulf of Mexico.
Spend some time on
the Florida Gulf Coast,
you will see a USO.
These objects are flying along,
uh, through the atmosphere,
and then suddenly,
they go into the ocean.
No splash, no wake, nothing.
They just go
right into the water
and then come out of the water
in many cases, and fly away.
Now, one such never
came out of the water,
and a submarine was actually
dispatched to look for a craft
that may have crashed,
but never found anything.
The stresses and strains
by flying through
the atmosphere,
in outer space and then
plunging into the oceans
would be enough to rupture
any of our known aircraft.
For ancient astronaut theorists,
perhaps the most
compelling story
of an extraterrestrial
presence in Earth's oceans
can be found in an account
from 1492,
recorded by
Christopher Columbus.
There's a famous story
about Christopher Columbus
and he wrote this
in his journals
that as he was moving
west across the Atlantic,
towards the Caribbean,
in his first voyage,
he saw a light out
in the ocean to the west,
hovering over the water.
And this light then
descended into the water.
So, he's perhaps one of
the first witnesses to describe
a trans-medium craft like this,
which could hover,
uh, above the water
and then disappear
into it like a submarine.
Stories of undersea objects,
glowing objects
that fly out of the water,
have been around
for well over
thousands of years.
Are these machines
that the extraterrestrials
have under the water?
There is only one mystery
left on our countdown,
and you don't want to miss it
because what was discovered
just may be evidence of
an underwater alien base.
On Ancient Aliens,
we've investigated
the ocean's biggest mysteries
for evidence of extraterrestrial
contact in the distant past.
But recent satellite images
may suggest that
otherworldly beings
are inhabiting our oceans today.
Number one on our list
of the top ten
mysteries of the deep:
Underwater Alien Bases.
With almost
200 miles of coastline,
this picturesque region
is famous for its beaches,
surfing and abundant sea life.
It is also a hotspot
for sightings of mysterious
lights in the water.
Folks have seen lights
in the water outside Point Dume
off the Malibu coast.
There is this
very strange 911 call
from an observer
near Point Dume,
saying he saw a light
coming out of the water
and calling it into
the sheriff's station.
One theory about this
trans-medium travel
and these USOs
is that what we're seeing
is evidence of underwater bases.
They're operating here,
but under the oceans,
right under our noses.
While the idea of
underwater alien bases
in Earth's oceans may
sound like science fiction,
in 2014, satellite imagery
revealed a very curious
formation on the seabed
six miles off
the coast of Malibu.
The satellite photos
show what seems to be
an oval, flat-topped structure
that's got legs coming
down that are holding it up.
It's about
2,000 feet underwater.
A lot of people got
very excited by this discovery.
It's really quite striking,
and it really does
look artificial.
And it makes you
wonder, is this,
as some believe,
an extraterrestrial base?
Is there a connection
between the strange lights
seen in the waters off
the coast of Southern California
and the mysterious
undersea structure
captured in the satellite image?
For some scientists,
it's a distinct possibility.
If all these objects
are buzzing our aircraft,
they must have
a base of operations.
But you see, if they have
a base of operations
that's easily detected
by us humans,
it would sort of defeat
the purpose of observing us.
So, perhaps there's
an underwater base
that is away from
prying eyes of humans
so that we don't
interfere with their plans.
That cannot be ruled out.
While the formation
discovered deep in the ocean
off the coast of Malibu
is highly unusual,
it is not entirely unique.
Across the globe,
mysterious anomalies
have been detected on the seabed
that some suggest are
underwater alien structures.
The under ocean
geological survey
determined that there were
dome-like structures
between Cuba and
the coast of Florida.
Was that a USO base?
Because underwater,
underneath our oceans,
best place,
the very best place
to conceal yourself.
Absolutely anything
could be hiding within
the oceans themself.
And the depths of them
could hide vehicles,
could even hide bases,
uh, for hundreds,
if not thousands of years.
We would not be aware
of their presence.
The oceans have everything
that the crew of a ship
would need to survive.
It's got plants and animals
that can be harvested for food.
There's minerals and salt
that can be taken
from the water.
You can even
separate the hydrogen
from the oxygen in the water
to create fuels
and-and air to breathe.
Everything that is
necessary for life
can be found in the oceans,
and it may be that
if extraterrestrials
are in our oceans,
they're not just hiding there,
this may be
their preferred environment.
The idea that alien
bases might be hidden
on the ocean floor
is incredibly thrilling.
But while much of
the ocean's depths
remain impossible to explore,
ancient astronaut
theorists believe
that the deeper we go,
the closer
we'll get to the truth
about mankind's
extraterrestrial past.
