All language subtitles for Ancient Aliens s19e20 The Top Ten Alien Petroglyphs.ecng

NARRATOR: 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.

NARRATOR: 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.

ROBERT SCHOCH: 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.

HUGH NEWMAN: 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.

NARRATOR: 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.

(speaking Japanese)

TRANSLATOR: 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.

TSOUKALOS: 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.

NARRATOR: 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?

ROB SIMONE: 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.

NARRATOR: 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.

DAVID CHILDRESS: 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.

NARRATOR: 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.

NARRATOR: 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."

WILLIAM HENRY: 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.

NARRATOR: 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.

SCHOCH: 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.

NARRATOR: 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.

NARRATOR: 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.

CHILDRESS: 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.

YOUNG: 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.

NARRATOR: 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.

NARRATOR: 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.

PAULINA ZELITSKY: I was in
control room on board of the ship.

There suddenly appeared

a very large, very dark images

of, uh, perfect
geographical shapes.

NEWMAN: 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.

COLLINS: And almost certainly,

this dates back
several thousand years,

and arguably even earlier,

and is part of a
lost civilization.

NARRATOR: 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.

CHILDRESS: 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.

NARRATOR: 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.

NARRATOR: 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.

CHILDRESS: 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.

NARRATOR: According to Plato,

this metal was given
to the people of Atlantis

by the Greek god Cadmus.

JASON MARTELL: 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.

NARRATOR: 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.

NARRATOR: 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.

SCHOCH: 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.

NARRATOR: 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.

CHILDRESS: 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.

TSOUKALOS: In
fact, ancient India,

their entire pantheon
of gods is based

exclusively on a cosmic origin,

that they arrived
from deep space.

NARRATOR: 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?

CHILDRESS: 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.

NARRATOR: 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.

COLLINS: 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?

NARRATOR: 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.

COLLINS: 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.

NARRATOR: 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.

TSOUKALOS: 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.

NARRATOR: 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.

SHIMKHADA: 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.

NARRATOR: 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.

CHILDRESS: 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.

NARRATOR: 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."

SCHOCH: 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.

TSOUKALOS: 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.

NARRATOR: 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.

TSOUKALOS: We have cart ruts

that go into the
Mediterranean Sea.

And then they also come
out on the other side.

How is this possible?

NARRATOR: 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.

NARRATOR: 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.

HENRY: 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.

NARRATOR: 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.

NARRATOR: Hitachi
Province, Japan.

1803.

Local fishermen are astonished
when a mysterious metal craft

washes ashore that is unlike
anything they have ever seen.

NICK POPE: 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.

NICK REDFERN: 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.

POPE: The story
of the strange craft

appears in three
different Japanese texts.

Even today, modern historians

struggle to understand
what this means.

NARRATOR: 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.

POPE: 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.

NARRATOR: Navy personnel
aboard the USS Omaha

capture footage of a
mysterious round object

flying into the ocean.

TAYLOR: 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.

NARRATOR: Japan. China.

San Diego.

These are just three
out of hundreds of reports

of what are known as "USOs."

BILL BIRNES: 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.

TAYLOR: 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.

KAKU: 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.

NARRATOR: 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.

BIRNES: 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.

NARRATOR: 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.

BIRNES: 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.

POPE: 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.

NARRATOR: 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.

CHILDRESS: 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.

POPE: 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?

NARRATOR: 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.

KAKU: 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.

NARRATOR: 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.

COLLINS: 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.

CHILDRESS: 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.
