NARRATOR: Thousands of years ago,

people all over the world described encounters

with enormous, humanlike beings.

WILLIAM HENRY: In ancient mythologies,

from the Greeks to the Nordics to the Native Americans,

we have these legends of giants.

NARRATOR: Giants can be found throughout ancient artwork.

You see really interesting figures depicted

that are infinitely larger than regular humans.

NARRATOR: And some archaeologists

even claim to have found human bones

of extraordinary size.

JIM VIEIRA: Smithsonian scientists uncovered

dozens of enormous skeletons.

NARRATOR: Could it be that the otherworldly giants

of myth and legend truly existed?

ANDREW COLLINS: I think that what we have today as a civilization

was given to us by the giants.

NARRATOR: Writing in the French scientific journal Archeologie,

German geophysicist Jörg Fassbinder and his team

reveal an extraordinary discovery

that they made along the banks of the Euphrates River.

While mapping the ancient Mesopotamian city of Uruk,

the archaeologists found something remarkable

hidden deep underground.

The German archaeological team used magnetometers

to survey the ground beneath

what is believed to be the city of Uruk.

They found a number of underground structures,

but the one that got them the most excited

was the discovery of a very large tomb.

NARRATOR: What makes this discovery particularly exciting

is its potential connection

to the oldest known story ever written,

called the Epic of Gilgamesh.

The more than 4,000-year-old Sumerian text

describes King Gilgamesh,

who most experts believe was a historical figure.

And it describes that Gilgamesh was buried

beneath the ancient Euphrates River

exactly where the German archaeological team

detected an underground tomb.

German archaeologists thought

that they had actually discovered

the tomb of King Gilgamesh.

It was right down on the riverbed

where it was described to be.

So they were pretty much sure

that they had found the actual tomb of King Gilgamesh.

NARRATOR: According to some researchers,

finding the remains of King Gilgamesh

might be the greatest

archaeological discovery of all time,

because Gilgamesh was described as a giant.

HENRY: The ancient texts say that Gilgamesh stood

an astounding 11 cubits tall,

which means he would be about 17 feet tall.

Obviously, a giant.

And Sumerian scholars believe that Gilgamesh was

a real historical figure.

So, if the structure that the German archaeologists found

is, in fact, the tomb of Gilgamesh,

then what they've discovered was the tomb of an actual giant.

NARRATOR: Is it possible that the tomb of a giant

lies hidden beneath the earth in southern Iraq?

Before the German archaeologists could find out,

Iraq became embroiled in the Second Gulf War,

and the team was forced to flee the country.

But ancient astronaut theorists find it intriguing

that the hero of humanity's oldest known story

is of giant proportions.

In fact, throughout the ancient world,

nearly every culture told stories of giants.

HENRY: When we look at the stories of the giants,

it's a global phenomenon.

From North America, South America,

throughout the Middle East, there are stories

of these enormously powerful, very tall beings.

GIORGIO A. TSOUKALOS: Every ancient culture speaks of

a long-lost time when the so-called giants

still mingled amongst human beings.

For example, the First Nations people of Australia,

their original creator gods, the Wandjinas,

are depicted as these giant, tall beings.

In ancient Greece, we have stories

of the so-called Cyclops,

these giant, tall beings with one eye in their forehead.

And in the ancient Veda texts,

the original Buddha allegedly was 12 feet tall

with blue skin

and hands that would go down below to his knees.

He was this giant man that imparted knowledge.

The fact that we have these stories worldwide

illustrates to me that there had to have been

a common denominator.

NARRATOR: If giants truly existed in the distant past,

what were they?

Ancient astronaut theorists suggest

that some accounts of giants reveal that they were

something other than just humans of extraordinary size,

like the ancient stories from Ireland that tell

of mysterious visitors known as the Tuatha Dé Danann.

HENRY: The Tuatha Dé Danann descended from the sky

in ships and landed upon the mountains.

These mysterious beings were giant demigods

that possessed some advanced technology

that they ultimately used

to create some of the most incredible

megalithic constructions ever created.

NARRATOR: The Tuatha Dé Danann are sometimes credited

as being the builders of enormous passage tombs

like Newgrange, Knowth and Dowth.

And, in fact,

many ancient megalithic sites around the world

are associated with giants,

like the Ggantija temple in Malta,

which is believed to be more than 5,000 years old.

In Malta, you have some of the most ancient

and most gigantic megalithic sites on Earth.

One of these megalithic structures in Malta

is called Ggantija,

because it comes from the giant.

In fact, it was a woman giant that gave birth to giant twins,

and she created some of these structures

in order to protect her children.

NARRATOR: In the 17th century,

a Maltese nobleman named Gian Francesco Abela

claimed to have found evidence

that these legends may have been based in fact.

HUGH NEWMAN: Gian Francesco Abela claims

to have found not only giant skeletons

but skulls, teeth

and other bone fragments all across the island of Malta.

But also, other people

have reported on them, as well, at this time.

NARRATOR: Other megalithic sites connected to stories of giants

include the so-called Tombs of the Giants in Sardinia,

the Greek archaeological site of Mycenae

and Baalbek in Lebanon.

VIEIRA: Traveling the world, you will find the same story.

It's ubiquitous.

Megalithic sites are associated with giants,

supernatural beings,

strange technologies,

and the legends are very explicit.

They're unambiguous.

NARRATOR: One ancient site that has long been associated with giants

is the famous megalithic structure in England

known as Stonehenge.

VIEIRA: The original name of Stonehenge was

the Giants' Ring or the Giants' Dance.

That's the Welsh name.

What's noteworthy is

the earliest representation of Stonehenge

has Merlin, King Ambrosius

and a 12-foot giant building Stonehenge.

NARRATOR: The image appears in a mid-14th-century manuscript

illustrating an account in a much earlier text

called The British History.

Written by Geoffrey of Monmouth in 1136,

the book recounts how the wizard Merlin

used powerful magic and the help of giants

to transport and construct the massive Stonehenge monument.

While the story may sound like the stuff of fantasy,

there have been multiple reports of giant bones

being discovered near the ancient stone circle.

NEWMAN: In the general area around Stonehenge,

numerous skeletons have been unearthed

over the last 600 years that suggest that giants

actually resided in this immediate area.

In the early 1500s,

Thomas Elyot, who was a well-known scholar,

discovered with his father Richard Elyot

at a place just south of Stonehenge

a 14-foot, ten-inch skeleton

in a wooden oak coffin.

And it also had this strange metal disc--

very large, almost like a tabletop disc--

made of lead and tin with these very strange inscriptions on it.

Elyot was very well respected, a member of Parliament,

and he recorded this several times in the historical record.

NARRATOR: Was a giant skeleton,

buried with some kind of mysterious artifact,

really unearthed at Stonehenge?

Could it be that thousands of years ago,

humans encountered otherworldly beings of enormous proportions?

Ancient astronaut theorists say yes

and suggest there is even evidence

that giants walked the Earth in much more recent times,

as recorded in the ship logs

of some of history's greatest explorers.

NARRATOR: It is less than three months since the start of World War I,

and the front page of The New York Times

is dominated by headlines about the global conflict.

But on page nine, a sensational article

documents the incredible discoveries

recently made in South America

by Australian explorer Captain James Besley,

which include the bones of an eight-foot-tall man.

VIEIRA: In 1914, Captain Besley led an expedition in Peru

where he unearthed a giant skeleton

with a huge, elongated skull.

He wrote about it. He discovered it.

He reported it.

You know, what's interesting is, in the historical record,

there's many accounts of giant skeletons

being unearthed in the Lake Titicaca region.

Some were enormous-- eight-, nine-, ten-foot-tall skeletons.

Now, sometimes these are animal bones

that at the time were, uh, misunderstood.

But oftentimes, they are human burials

with human artifacts, elongated skulls,

but a lot of it seems to be lost to history.

So it's still open-ended as to what happened to the bones.

NARRATOR: Is it possible that skeletons of giants

standing as much as ten feet tall

were discovered near Lake Titicaca?

While the finds were well-documented,

what happened to these allegedly giant,

humanlike bones remains unknown.

But researchers point out

that when Spanish conquistadors first arrived

in Peru in the 1500s,

the Native people told them stories

of giants that once inhabited the entire region.

TSOUKALOS: In 1553, the Spanish conquistador Pedro Cieza de León

wrote in his chronicles of Peru

that the Native people told him about giants

who arrived in the area long ago.

And according to local traditions,

their ancestors encountered people so tall

that an ordinary human

would only come up to their knees.

And Pedro Cieza de León also claimed

that some of the Spaniards found a giant shin bone

and a giant tooth.

NEWMAN: There are accounts of giants existing

around the area of Lake Titicaca in the Peru, Bolivia,

Altiplano area.

The Inca said that there was a tradition

of these giants called Huaris

building sites like Tiahuanaco and Puma Punku

long before the Inca or any other cultures existed there.

We also have stories, even at Tiahuanaco itself,

that the great founder god Viracocha,

who emerged from Lake Titicaca,

created a race of giants from the earth, from the mud,

and controlled them

so they would build the megalithic sites

in the area, like Tiahuanaco and Puma Punku,

before they were then vanquished by a great flood.

The historical record and the legends

seem to be telling us about giant humanoids

existing in the past and being associated

with megalithic building.

NARRATOR: For ancient astronaut theorists,

the stories of giants and alleged discoveries

of giant bones in Peru are compelling.

But even more intriguing is the fact

that some of history's greatest explorers

claimed to have actually seen giants in South America

with their own eyes.

Sanlúcar, Spain.

September 8, 1522.

After more than three years at sea, the Victoria,

a ship launched by Portuguese explorer Ferdinand Magellan,

sails into the harbor.

Its arrival completes the first circumnavigation of the globe.

As recorded in the ship's log,

Magellan and his crew faced dangerous storms,

fierce battles and grand receptions.

But for many, the most intriguing account

detailed an unusual encounter near the tip of South America.

TSOUKALOS: Ferdinand Magellan and his crew were approaching land

near the southernmost point of South America when,

according to the expedition's official chronicles,

they encountered these towering giants

who apparently stood twice as tall as a normal human.

ANTONIO PIGAFETTA (dramatized): We saw a giant,

who was on the shore of the sea,

quite naked, and was dancing and leaping and singing.

He was so tall that the tallest of us only came up to his waist.

However, he was well-built.

The captain named this kind of people Patagon.

NEWMAN: They witnessed these extremely tall

human Natives of the area,

and he actually named the area Patagonia

because it translates as "Land of the Big Feet."

And these clearly had very big feet, as these were giants.

VIEIRA: According to the logs of the Victoria,

Magellan took back two of these giants on his voyage home

with the goal of presenting them to the court in Spain.

But they became so sick and died,

they had to be thrown overboard.

NARRATOR: Is it possible that Ferdinand Magellan,

one of history's most celebrated explorers,

encountered actual giants in Argentina?

Researchers suggest the story might be more easily dismissed

were it not for the fact that a similar encounter with giants

was documented by another famous explorer in South America.

The account came from Dutch ship captain Jacob Roggeveen

and his crew in 1722

after they arrived at a mysterious spot

off the coast of Chile

that Roggeveen would later name Easter Island.

NEWMAN: The Dutch explorers of Easter Island,

not only did they witness Polynesian types on the island;

they also witnessed these very tall people,

which they called giants.

And the strange thing about them--

they look quite different to the native Polynesians.

They were much taller.

They had red or auburn hair.

And in some cases, they described them

as having fairer skin than the Polynesians

of that particular island.

DAVID CHILDRESS: So here we have people seeing giants in South America.

And you hear stories

in other places, too,

where people encounter what they say are

extremely tall giants.

And it seems incredible,

but it's certainly, you know, not impossible.

NARRATOR: Could explorers in South America

have encountered real-life giants

just a few hundred years ago?

While the accounts of men like Ferdinand Magellan

and Jacob Roggeveen are truly incredible,

researchers say that evidence of giants is even more abundant

in North America.

NARRATOR: At Lovelock Cave,

two miners are collecting bat guano

to be used as fertilizer.

One layer of guano they remove is estimated to weigh 250 tons,

and within it they discover incredible ancient artifacts.

We know, from the historical record,

that these excavations occurred.

And they began finding artifacts--

duck decoys,

huge woven shoes for-for giant feet--

and eventually, they found a number of skeletons,

complete skeletons of people with red hair

who were almost eight feet tall.

And there were two museums in Nevada

created for these giant skeletons.

Today, we don't know where any of those skeletons are.

They are not on display.

NARRATOR: Could the remains of redheaded giants

have been unearthed within Lovelock Cave?

While the bones allegedly recovered in 1911

have since gone missing,

researchers find it compelling that the Native Paiute people

have oral traditions involving red-haired giants.

NEWMAN: The first account

of these red-haired giants at Lovelock Cave

was written about by Sarah Winnemucca Hopkins,

who was the daughter of a chief

of the Paiute tribe.

In 1893, Sarah Winnemucca published

a book about Paiute history

in which she recounted her people's battles

with a giant called Sai-duka'a.

The Sai-duka'a was said to have been white-complected,

having red hair, and well over seven foot tall.

The Paiutes explained that these giants created

so much of a problem that the Paiutes had 350 warriors

take care of this problem once and for all.

NARRATOR: While there are many skeptics who question her story,

Sarah Winnemucca Hopkins was a highly respected figure

who even met with U.S. President Rutherford B. Hayes

to advocate for the humane treatment of her tribe.

A bronze statue honoring her stands prominently

in the Capitol Visitor Center's Emancipation Hall

in Washington, D.C.

Now, what's fascinating is that Sarah Winnemucca says

that this was an actual battle.

This wasn't folklore.

This was a battle that actually happened.

JON DOVER: The Paiutes were warring with them

for many, many years.

The giants were said to attack tribal members

and take them and devour them.

And so, finally, the, uh, tribe just decided that's enough

and set out on a major campaign.

And what they found was that these giants were inhabiting

a large cave.

And they piled up brush on the outside and set a fire...

...and directed the smoke into the cave,

thereby suffocating all the inhabitants.

NEWMAN: What is interesting about the discovery

in 1911 at Lovelock Cave in Nevada

was the fact that it showed evidence of extreme burning,

like fires had been lit inside the entrance to the cave.

And this matched the story of Sarah Winnemucca Hopkins

from her writings.

NARRATOR: Sarah Winnemucca's ancestors not only passed down to her

the story of their war with giants

but also a physical relic

taken from their fallen enemies.

NEWMAN: We have evidence of red hair

because she actually saved some of the hair

and sewed it into a mourning dress,

which she used when she gave lectures.

NARRATOR: As far as ancient astronaut theorists are concerned,

Lovelock Cave and the stories surrounding it

provide strong evidence

that there were giants on Earth in the distant past.

And it is just one of many sites in North America

associated with giants.

In the 19th century,

Jesuit missionaries traveling through this area

came upon what is now known as the Painted Cave of El Carmen.

Adorning the cave walls, they saw giant figures

that somewhat resembled humans

but with extra digits on their hands and feet.

VIEIRA: What's fascinating is

when the Jesuits showed up and spoke to the Cochimí people

who lived in the area in the 1700s,

they claimed that a race of giants made the rock art there.

They said they came from the north, male and female.

And when you look at the rock art,

you have these giant beings,

and they have six fingers on their hands,

which is very interesting.

Polydactyly is a rare genetic condition in humans.

And it causes the growth of extra digits,

extra fingers, extra toes.

But in the ancient world, it's associated with the divine,

the supernatural and giants.

In fact, from places like isolated Pacific islands,

Australia, Botswana, Africa, Malta, the American Southwest,

you have extra digits associated with giant beings.

Now, it's pretty specific iconography

to be found in cultures that had little or no contact.

NARRATOR: Descriptions of giants with extra fingers and toes

can even be found within the pages

of the Bible's Old Testament.

TSOUKALOS: In 2 Samuel 21:20,

it says there was a war at Gath

where there was a man of great stature

who had six fingers on each hand

and six toes on each foot.

And he also was born to the giants.

So here we have a biblical description

of a giant with six toes and six fingers,

very similar to what we see in that petroglyph in Mexico.

NARRATOR: While the mysterious cave art

and the stories told by the local Cochimí people

are intriguing, for many researchers,

what's most compelling about the Painted Cave of El Carmen

is that, just like Lovelock Cave in Nevada,

it was allegedly found to hold the remains of giants.

The Jesuits, in their records, actually reported

unearthing giant bones

and believed that giants lived there

because of what the Cochimí told them.

But it's still open-ended as to what happened to the bones.

What's noteworthy, however, is that you have a situation

where myth and oral tradition

is lining up with the Jesuits' own records.

NARRATOR: Do the oral histories, petroglyphs

and alleged discoveries of enormous humanlike bones

reveal that giants once inhabited North America?

While the evidence is certainly compelling,

for ancient astronaut theorists,

the most convincing accounts are those that are backed up

with photographs.

NARRATOR: Sonora, Mexico.

The early 1930s.

American explorer Paxson Hayes

is researching local snake species

while living among the Indigenous Yaqui people.

His studies take place over several years,

and as he gains the trust of the Yaqui,

they begin to tell him about strange happenings

in the region.

Paxson Hayes respected their culture,

so he was brought in, and-and...

and these oral traditions of giants were shared with him.

The Yaqui, like so many other tribes,

firmly believed that there were giant beings that existed.

NARRATOR: The Yaqui said that according to their traditions,

somewhere nearby was an entire lost city of giants,

and Hayes set out to find it.

In 1935, he claimed to have succeeded.

According to Hayes, the city he discovered

appeared to be thousands of years old.

And what he found there was astounding.

VIEIRA: Paxson Hayes reported to find 34

seven-and-a-half-foot mummified giants.

Now, I have the original press release

that show one of the mummified giants bundled up that he found

and a giant mummified head and this enormous gourd.

So there's visual proof.

Paxson Hayes was quite blown away

by all these discoveries that were being made.

But he lost all his funding

to continue the exploration and research.

And the lost city has never been found since, incidentally.

NARRATOR: Could it be that the remarkable claims of Paxson Hayes are true?

Perhaps further clues can be found

by examining reports of another extraordinary discovery

made in the American Midwest.

Throughout the Ohio Valley,

we have what's called the Adena burial mounds.

And these are, in a sense, pyramids or mounds.

And starting in the mid-1800s or so,

they began to excavate.

And what these early archaeologists discovered

was quite astonishing.

They were getting skeletal remains

of people who were giants.

Miamisburg Mound in Ohio is one of the largest

Adena burial mounds in the region.

Numerous digs took place in this particular mound

and other mounds in the area.

And in 1856, a remarkable discovery was unearthed

of an eight-foot, two-inch skeleton

within the mound itself.

Now, this caused a kind of sensation in the local area.

It was reported in great detail.

Medical doctors and scholars looked at it.

But the Smithsonian didn't really follow up

and do some proper research and analysis.

When it comes to studying

the so-called giant remains of North America,

the Smithsonian, they just kind of ignore

any anomalies, anything that's out of the ordinary

that doesn't fit their preexisting paradigm.

NARRATOR: The Smithsonian routinely dismissed reported discoveries

of giant bones.

But records filed by the institute's own archaeologists

document the discovery of numerous oversized skeletons

throughout the Ohio Valley.

The Smithsonian's own scientists have dozens

of recorded instances of the unearthing

of eight-foot-tall inhabitants,

36-inch-circumference skull

found by T.M. Perrin in Illinois.

It's all in the record.

NARRATOR: But if the Smithsonian discovered giant bones,

why would they later cover up their existence?

Some researchers suggest

scholars are simply unwilling to entertain the notion

that something long relegated to the realm of fantasy

could be real.

The idea of giants belongs to this, uh,

mythological, religious realm

of the ideological enemy of science.

So the incredible intellect of many people are spent

debunking, marginalizing and mocking these ideas.

But right in the records we have another story.

NARRATOR: While the Smithsonian continues to claim

that giants belong to the realm of fantasy,

many Native American tribes

consider these supposedly mythic beings

as part of their history.

DOVER: Native Americans have a tradition

of oral history.

That history has to be said exactly as it happened.

It can't be embellished.

Part of this tradition is that in the past,

there were giants here on the Earth.

In Navajo culture, you have the Hero Twins

that were specifically trained to fight giants.

And they were known as the giant slayers.

HENRY: According to the story,

the twins emerged from an abalone shell

and turquoise that fell from the sky.

They were raised by a local woman.

And when they grew older, they were told

that giants had been harassing their people.

And they later went on a journey to defeat these giants.

NARRATOR: According to Navajo mythology,

a powerful sky being named Tsohanoai,

or "the Bearer of the Sun,"

gave the twins powerful weapons to aid them in their quest.

JASON MARTELL: One of the twins was given a magical bow and arrow

that could hit its target with unwielding precision.

The other twin was given a type of staff

that could somehow protect both of them.

Now, these weapons were said to have been given to them

by a god that descended from the sky.

To me, this doesn't sound like magic.

It sounds like some type of misrepresentation of technology,

possibly given to them by extraterrestrials.

NARRATOR: Is it possible

that the Navajo story of the Hero Twins

is an account of historical events

that involved not only real-life giants

but also extraterrestrial intervention?

Perhaps further clues can be found

by examining the writings of a famous 19th-century mystic

who taught that long ago

Earth was ruled by a towering race of beings

who possessed highly advanced technology.

NARRATOR: Famous Russian mystic and philosopher

Madame Helena Blavatsky founds the Theosophical Society,

an esoteric organization

that explores theories on the origins of humanity.

The Theosophical Society was, um,

the most influential esoteric

or spiritual organization in the late 19th century.

One of the earliest people to join was Thomas Edison,

who was working on the light bulb at the time.

And W.B. Yeats,

the Nobel Prize-winning Irish poet,

was an early member of the Theosophical Society.

Abner Doubleday, who was the Civil War hero,

inventor of baseball.

And one person whom Madame Blavatsky had

an enormous impact on was Mahatma Gandhi.

Blavatsky starts out as a... as a product of her time

in that the spiritualist movement

is spreading across Europe,

and she really takes it to a new level

and in her early adulthood goes off on these

sort of grand adventures

to discover what's out there in the world of esoterica.

And these adventures take her to Tibet,

and she begins to communicate

with intelligences referred to as mahatmas

or masters or ascended masters.

NARRATOR: Madame Blavatsky claimed to have been contacted

by an ascended master she called Koot Hoomi,

who lived in the mountains of Tibet.

Madame Blavatsky believes that she is bringing forth

this ancient wisdom.

And she demonstrates through a type of channeling,

and she is bringing forth information

from this brotherhood of ascended masters.

NARRATOR: According to Blavatsky,

Koot Hoomi brought to light new information

about humankind's ancient past,

which includes ages in which giants walked the Earth.

She shared these revelations in her controversial book,

The Secret Doctrine.

GARY LACHMAN: She wrote this enormous work called The Secret Doctrine.

And this is an occult history of the universe,

and it includes the notion that there were

previous civilizations, what she called root races.

In her view, humanity went through

or will go through seven epochs or cycles

in its development, beginning with the first root race,

which she called Polaria.

This was considered to be an astral race

that lived in one of the polar regions.

The second root race,

she referred to as the Hyperboreans.

They lived at the North Pole.

And then she describes the third root race,

the Lemurians,

who are described as towering figures.

They are this advanced race of giants

that is followed then by the fourth root race,

the Atlanteans.

And then she describes us as actually living

in the fifth root race, which is a combination of a spiritual

and a material being.

NARRATOR: According to Blavatsky's book,

while there is a progression

from one root race to the next,

it is not a straight line of evolution,

and both the third and fourth root races,

the Lemurians and Atlanteans,

had technology and spiritual awareness

superior to modern-day humans.

A different cosmology that included

giants and normal people,

different races that existed in the past

and then were replaced by another root race.

NARRATOR: The concept of root races

was also espoused by Edgar Cayce,

a world-famous psychic in the early 1900s.

He, too, saw giants in Earth's past,

not only among the Lemurians and Atlanteans

but also in North America.

CHILDRESS: The famous psychic Edgar Cayce, as well,

talks about kind of root races and giants.

And with Edgar Cayce, he talks about them having,

you know, advanced technology.

HENRY: When viewed through the lens of ancient astronaut theory,

they are very clearly describing this advanced race of giants

that possessed technology that was considered to be

superior to what humans possessed at that time.

You could open up a line of speculation

that these giants had an extraterrestrial connection,

if not being extraterrestrials themselves.

NARRATOR: Could it be that highly evolved beings of giant proportions

were at the heart of an advanced civilization

that existed on Earth long before our recorded history?

According to some researchers, the answers may lie

within a forbidden book of the Holy Bible.

The Christian church holds a secret meeting

called the Council of Laodicea

to discuss the removal of certain books

from the biblical canon.

Among them is the Book of Enoch.

Why it was determined that this book

should be stricken from the Bible

is the subject of much debate,

but many biblical scholars suggest it was due to

controversial stories involving the Watchers,

a group of 200 angels

who were tasked with watching over humankind.

COLLINS: The Watchers came down from heaven

to mix with mortal-kind.

They were said to have revealed the arts and sciences of heaven,

and this allowed us the rudiments of civilization.

But what's so interesting is that these rebel Watchers

were also said to have taken human wives,

and the wives gave birth to giants known as Nephilim.

This is handed down in the Book of Enoch

absolutely clearly.

When the sons of the gods saw that the daughters of man

were beauty, they took them to wife,

and the product of it were giants.

Just look at these old myths with modern languages.

Change the word of "angel" into "extraterrestrial."

These giants were a mixture

between humans and extraterrestrials.

The Nephilim are this hybrid offspring

that were extremely powerful

and described as very tall.

They were also threatening to humanity.

In fact, we're told that the flood of Noah

was sent to destroy the giants.

But there were survivors,

and there were eyewitness accounts

of giants after the flood.

In the Book of Numbers, the sons of Anak were giants.

Goliath is cited as another of the descendants of these giants,

very tall in stature, very powerful being.

TSOUKALOS: The Book of Enoch used to be part of the Bible.

This book contained, in my opinion,

explosive topics.

Because certain books of the Bible were removed,

and you have to ask the question, why?

NARRATOR: According to ancient astronaut theorists,

the Book of Enoch provides compelling evidence

for not only the existence of giants on Earth

but also their extraterrestrial lineage.

What leads me to think that the stories

of the giants may be true

is that not only do we find

stories of giants in the Book of Enoch

and on pretty much every continent,

but the stories are essentially very similar, if not identical.

NEWMAN: The stories of giants are generally regarded

by most people as kind of bedtime stories

you read to your children at night.

But so much has been written in the academic record

by doctors and town and county histories

and other sources.

And so, there really is a reality to these giants

that existed throughout history.

This can't be just a case of cultural diffusion,

that people all over the world are creating the same stories.

Instead, to me, it suggests that humanity has been dealing

with beings referred to as giants for all these millennia.

CHILDRESS: I think the big question is, here, you know,

is there some extraterrestrial race that are giants

who have been here in the past interacting with humans

and that they're even still here today?

NARRATOR: Are stories of giant beings,

repeated in culture after culture,

and reports of enormous human remains

evidence that a lost race of giants once walked the Earth?

And if so, are certain groups

working to conceal this truth from the public?
