NICK REDFERN: If the theory of evolution is correct,

we should see a steady, slow progression.

We're actually not seeing that.

DAVID CHILDRESS: What we're seeing, really,

is something like out of The Lord of the Rings.

GEORGE NOORY: You have a group of people indigenous

to this planet, and you really can't trace

what their ancestry was.

The planet has been an experimental lab.

WILLIAM LEONARD: At this point, we don't know exactly why

these other species died off.

GIORGIO TSOUKALOS: Could this be an experiment

by extraterrestrials where, in the end,

only Homo sapiens survived?

NARRATOR: Since the dawn of civilization,

mankind has credited its origins to gods

and other visitors from the stars.

What if it were true?

Did extraterrestrial beings

really help to shape our history?

And if so, might the proof be found

by investigating the prototypes?

NARRATOR: Temple University, Philadelphia. 1992.

History professor Dr. David Jacobs

releases his book Secret Life.

After over 30 years of collecting research data

and interviewing hundreds of individuals

claiming to have been abducted by extraterrestrials,

Jacobs became convinced that aliens were using Earth

as a genetic laboratory

to create a new species of alien‐human hybrids.

I've looked at about 1,150,

1,175 different abduction events,

and I became convinced that this was the real item,

that the people actually were being abducted.

And they all say the same thing, and it's global.

They're put on a table,

there are procedures that are applied to them.

Men have sperm taken from them;

women have eggs taken from them.

Very often, they're taken into other rooms

where they see babies who look odd,

look sort of like a cross between human and alien babies.

The question is: are humans being manipulated

to become a hybrid species themselves?

NARRATOR: Although critics acknowledge

that Dr. Jacobs' research is meticulous and methodical,

they continue to dismiss the abduction phenomenon entirely.

But could it be that extraterrestrials

are actually using human DNA

to add a new branch to the evolutionary tree?

Ancient astronaut theorists say yes,

and they suggest that,

while modern‐day abduction stories are compelling,

the answer might best be found

by examining mankind's very beginnings

and the numerous other human‐like species

with whom we once shared the Earth.

Gauteng Province, South Africa.

September 13, 2013.

Recreational spelunkers unearth a trove

of human‐like fossils deposited deep inside a cavern

known as the Rising Star Cave.

Paleoanthropologists determine that the bones

are remarkably distinctive

from any previously found early human remains,

and upon further examination,

decide that they are actually not human at all,

adding a startling new piece to the evolutionary puzzle.

They call this new species Homo naledi

to correspond with the Dinaledi chamber it was discovered in,

which translates to "chamber of stars."

What is remarkable about these hominids

is that they are a distinctive mix

of both primitive

and more advanced hominid characteristics.

So there are some elements of Homo naledi,

like the shape of the skull, the size of the teeth,

the feet, the ankles, that are very human‐like.

There are other characteristics, like the brain size,

only about 500 ccs,

so about a third of modern human brain size,

and also aspects of the shoulder and the trunk

that are much more primitive,

much more similar to our earlier hominin ancestors.

PETER WARD: The original thought is this might be,

really, the first humans of Africa,

seven to three million years ago.

But this cave seemed newer.

The way the bodies were placed seemed almost too regular.

It looked as if there was at least ceremony

to what was being done.

And that, of course, suggests this would be a fairly well‐on

evolutionary advanced creature.

NARRATOR: Finding the Homo naledi bones

is considered the most astonishing

human fossil discovery of the last 50 years,

as it adds a baffling new branch to the human family tree.

This is a tremendously exciting time.

Both the fossil and the genetic evidence

really underscore that there is much more diversity

in human forms in our evolutionary past

than we previously recognized.

NARRATOR: The hominin, or hominid,

branch of the evolutionary tree includes modern humans,

as well as the extinct human predecessors

such as Neanderthal,

Homo habilis, Homo erectus,

and other early, intelligent standing primates

that have long since vanished.

And despite many years of thinking otherwise,

scientists are now discovering

that many of these species co‐existed.

CHILDRESS: What we're seeing, really,

is something like out of The Lord of the Rings,

where we have all kinds of different humanoids

who are tall and short,

who have different color skins, different types of hair.

Even their brains are slightly different.

Some are more animals or apes.

Others are more refined.

NARRATOR: Some researchers suggest

that these recent discoveries may require a retooling

of Darwin's theory of evolution,

which was first proposed in 1859.

In his work On the Origin of Species,

Darwin laid out the foundation for evolutionary theory

by proposing that gradual multigenerational changes,

occurring due to natural selection,

would result in the modification of existing species.

If the theory of evolution is correct,

we should see a steady, slow progression.

We're actually not seeing that.

We're seeing the sudden surfacing of early humans

who are actually very highly evolved.

The scientific community explains everything away

by nothing else

but natural selection and coincidence.

And the intelligent design camp

suggests everything was done by God.

What if this external force did in fact exist?

But it may have been an extraterrestrial.

NARRATOR: Could it be that the evolution of humans,

and even prehuman hominin,

might not be entirely what Darwin proposed?

Might there be an even more profound explanation

for the different species of intelligent hominin

that once existed on Earth?

Perhaps clues can be found by exploring the details

contained within some of humanity's earliest stories

of our creation.

We have this notion that the people

that were the earliest examples of a civilization

were not the first attempts,

that there were failures that came before,

and finally they would come up with something better,

and that would be the prototype that became the people.

Sumerian texts speak of deformed humans

created by Enki and the mother goddess Ninhursag

in the course of their efforts to fashion a perfect person.

In all, six protohumans were made

before they came up with what they wanted.

In the Mayan text the Popol Vuh, "the Book of the People,"

it is said that there were three attempts to make people.

NARRATOR: Could the stories of gods creating

multiple versions of man‐‐

which can be found in the Mayan Popol Vuh,

the ancient Sumerian texts and other writings‐‐

be accounts of what actually happened on Earth

in the distant past?

And if so, just who were these gods?

There's a very good chance that early humans were possibly

genetically manipulated by advanced extraterrestrials

trying to formulate and create the ultimate human species.

What if at the heart of it is the concept

that the planet itself has been an experimental lab,

an experimental garden,

and that all of these different models getting to Homo sapien,

that there had been all kinds of models,

all for different reasons, all part of tests,

‐all done by DNA manipulation by nonhumans ‐(heart beating)

in the extraterrestrial category.

NARRATOR: Could the widespread mythologies

about the creation of various human prototypes

be real accounts of an extraterrestrial experiment,

an experiment that continues to this day?

Perhaps further clues can be found

by examining the fossil discovery

of real‐life hobbits.

NARRATOR: The Indonesian island of Flores,

just north of Australia.

September 6, 2003.

Archaeologists seeking evidence

for the first Homo sapiens migration to Indonesia

come upon what they believe is the skull of a human child,

embedded in the earth

20 feet beneath the surface of Liang Bua Cave.

After several days of careful excavation,

enough of the cranium and mandible are exposed

to reveal that the teeth belong not to a child,

but to a fully grown adult.

The skull, along with the skeletal remains

that were recovered weeks later, belong to an ancient hominin

that stood only three‐and‐a‐half feet tall.

Scientists name the species Homo floresiensis,

but they are more commonly referred to as "the hobbits."

The Flores hominids date to 16,000 to 18,000 years ago,

a time period when, we thought,

only anatomically modern humans existed.

What is remarkable about the Flores remains

is their tiny, tiny body size.

And as well, at least one of the specimens has a brain size

that is only about the size of a chimpanzee, 300 to 400 ccs.

And yet you have tools that are consistent

with anatomically modern humans.

How to reconcile that is still an open question.

CHILDRESS: The recent discoveries of these hobbits

on the island of Flores in Indonesia

has really rocked the anthropological world.

And anthropologists were really not aware

and didn't think that there would be

this miniature type of person,

who's a distinct species from Homo sapiens.

NARRATOR: Prehistoric stone tools

found on the island of Flores

suggest that these so‐called hobbits

may have arrived there 800,000 years prior.

How did this species get to the island?

So there are two options how this could have happened.

One is that these hobbit people arrived there on boats,

or they were planted there

by extraterrestrials in the remote past.

Some people even have suggested that this island served

as some type of a petri dish because of its isolation.

NARRATOR: Seven years after the initial Flores discovery,

archaeologists stumble across yet another new species

8,000 miles away

in the remote Altai Mountains of Siberia.

Isolated in a cave

at an elevation over 2,400 feet above sea level,

scientists discover a finger bone fragment and tooth

of a previously unknown prehuman

that existed at least 40,000 years ago.

They name the species Denisovan,

after the name of the cave that the bones were found in.

It's particularly fascinating that when we look

at the geographical distribution of the early humans,

they're in different parts of the world.

We have the Denisovans in Siberia and Russia.

We have Homo floresiensis on the island of Flores.

And the list goes on.

It begs the question: How would that happen?

Why would it not be the case

that multiple different types of human

would appear in multiple areas?

But they had their own geographical location.

NARRATOR: Discoveries made in just the last two decades

paint a picture of at least four distinct groups

of intelligent hominins

existing in isolated pockets of the world:

Homo floresiensis, isolated on the island of Flores,

Denisovans being found in the Altai Mountains of Siberia,

Neanderthal found occupying Western Europe,

and anatomically modern humans evolving in Africa.

Scientists don't entirely understand

the role of geographic isolation,

but what we know from studies of island populations

of both humans and nonhuman species today

is that isolated environments are fertile ground

for producing unique and distinctive adaptations

and also extremes in body size.

NARRATOR: In 1972,

renowned evolutionary theorist Dr. Stephen Jay Gould

proposed a modification to the standard model of evolution.

His punctuated equilibrium theory addressed evidence

that changes in the fossil record

came not as a steady process of gradual evolution,

as proposed by Darwin,

but rather in fits and starts.

And these rapid changes seemed to primarily occur

in situations of isolation.

His theory continues to be considered controversial,

as it also suggested that there must've been

an unknown mechanism at play.

But his research stops short of defining

what this could have been.

CHILDRESS: We don't have the step‐by‐step changes

that we were expecting to find.

So we have to ask ourselves, is there really

this slow random evolution?

Or are there sudden leaps,

where suddenly there is a new kind of species

that's just come straight out of the incubator?

And so it's like we have these different species of humans

that are being developed in isolation

in different parts of the world.

NOORY: I've always said that Earth

is a planet of experimentation.

I keep thinking of The Island of Doctor Moreau,

where you're sequestered in a certain area,

and you can conduct your work in quiet and in privacy.

And there would be no reason why they wouldn't want

to do this same thing here, rather than just

simply take people and take them to a different planet

and play around, which I think they do.

HOWE: Extraterrestrials would

use islands for one experiment,

tops of mountains for another experiment.

But they would control what they were doing by keeping

their different experiments separated from each other‐‐

oceans, mountains,

islands, peninsulas.

TSOUKALOS: If you subscribe to the zoo hypothesis,

which suggests that this entire planet is nothing else

but an experiment for extraterrestrial entities,

then one has to wonder:

Could this be an experiment by extraterrestrials

where, in the end, only Homo sapiens survived?

NARRATOR: Could remote areas of the globe

have served as extraterrestrial incubation sites

for protohuman development?

If so, was the experiment eradicated

to make room for the growth of Homo sapiens?

Perhaps further clues can be found by taking

a closer examination of our nearest evolutionary cousin‐‐

the Neanderthal.

NARRATOR: Sima de las Palomas, Spain. 2011.

Archaeologists unearth a prehistoric grave

containing three individuals

buried side‐by‐side with their arms folded

in a ritualistic fashion.

Because of the manner of their burial,

the archaeologists assume the remains are human,

but are surprised to discover that they are actually

our evolutionary cousin, Neanderthal.

It takes a good deal of imagination to prepare the dead.

It suggests some kind of notion of an afterlife.

If there is that,

there is usually a notion of a deity of some kind.

That is fairly complicated religious thinking,

suggesting that the Neanderthals had a capacity

for symbolic reasoning and the formation of culture.

This suggests a level of civilization,

or at least the proto‐culture,

that is further along than we used to think.

Neanderthals, unfortunately, because of early discoveries

that made them look like a brutish caveman,

not intelligent, that they're very, very different from us.

They were shorter and stockier, but they had huge brains.

They clearly had clothing.

They cared for their sick and elderly.

They were very intelligent.

NARRATOR: In 2014,

scientists analyzed materials

from 40 different archaeological sites

to determine a reliable extinction date

for Neanderthals.

The date they came up with is 40,000 years ago,

suggesting they coexisted with Homo sapiens

for at least 1,000 years.

But just why did they die off?

At this point, we don't know exactly why

these other species died off.

Certainly, it does broadly coincide with

the expansion of anatomically modern humans

to all parts of the globe.

But contrary to our notions from the past,

it doesn't look like it was a lack of intelligence

that led to the demise of Neanderthals.

NARRATOR: Although Neanderthals are long extinct,

in 2013, evolutionary geneticists discovered

select modern human populations

carry genomes from both Neanderthal and Denisovans,

suggesting that, at some point, interbreeding occurred.

Neanderthal genetic markers are concentrated in populations

in Europe and parts of the Middle East.

Denisovan markers can be found

in the mainland Asian populations,

as well as Pacific Islander, New Guineans

and Australian Aborigines.

According to some ancient astronaut theorists,

this interbreeding may be the key to understanding

the demise of the other intelligent hominin species

that once shared the planet with humans.

Consider the possibility that these different hominid strains

were meant to be kept

geologically separated from each other,

across tracts of land that were considered to be too vast

for them to ultimately come into contact with one another.

Is it possible that interbreeding was frowned upon,

and that once interbreeding with Neanderthals started

to take place,

it was damaging the very essence of the experiment?

And because of that, the Neanderthal strain

had to be terminated or removed from the planet

to stop this from happening.

REDFERN: When we look at ancient texts,

particularly religious texts, from millennia ago,

what we find is the idea of the gods or a god

wanting to create a human that was pure,

sort of physically and morally.

What we also find

are accounts where the wrath of God or the wrath of the gods

‐hammered down on us ‐(thunder crashing)

for essentially going off the rails, so to speak.

And we could make a case that this was some example

of extraterrestrial intervention to essentially try

and purify again the species,

and that might have involved wiping out significant portions

of early humans and starting over.

TSOUKALOS: About 70,000

and 40,000 years ago,

twice, at least twice,

Homo sapiens experienced a genetic bottleneck effect,

where the worldwide population of Homo sapiens

dwindled down to as few as 3,000 Homo sapiens

around the world.

So we have to ask ourselves:

Why did we survive,

and why did everyone else die out?

NOORY: It's very possible that the aliens decided

that in order to cleanse the planet,

they needed to do things of huge magnitude,

like the flood that the Bible talks about.

The flood was geared to primarily eradicating the people

that were on the planet at that time.

Well, God could have been the extraterrestrials,

‐could have created that somehow. ‐(panting)

It's very possible and very likely

‐that in order to eradicate a species ‐(people screaming)

that they may have genetically altered themselves

and screwed up with,

that they needed to get rid of them and start all over again.

NARRATOR: Did extraterrestrials eradicate

various prehuman species

in an attempt to keep the human genetic line clean?

Could the evolutionary bottlenecks in our prehistory

support this theory?

And just as evidence of interbreeding

exists in our genetic signature,

might there also have been unintended survivors?

NARRATOR: Emory University.

Atlanta, Georgia. 1998.

Researchers analyze DNA data

collected from various Native American populations,

in an effort to trace back their ancestral descent

through the Bering Strait.

The lineages are categorized into four haplogroups:

A, B, C or D.

Each line representing a different migration

off the Asian continent

between 20,000 to 30,000 years ago.

But what they also find

is that a small portion of the Native population

falls completely outside any previously known genetic group.

They can trace the ancestry back 36,000 years,

but not to the Bering Strait.

Scientists dub it the X lineage.

Among human haplogroups, one stands out:

the X lineage, which is found

in about 2.5 percent of some Native American groups,

and also in a small population

of northern Europeans and the Middle East.

And there is no connection between these groups.

We couldn't understand why they're so different,

these X haplogroups.

NOORY: Isn't it amazing that you have a group of people

indigenous, we think, to this planet

and you really can't trace what their ancestry was?

Scientists throw up their hands and they simply say,

"I don't know how this can be, because these people

"aren't somehow related to these people.

How can this be?"

NARRATOR: While the source of this X lineage

remains a mystery, some ancient astronaut theorists believe

it might be connected to a lost race of people

that were said to have existed throughout the world,

including North America.

CHILDRESS: It's possible that this X lineage gene

is related to the giants

that were reported throughout the world.

Starting in the mid‐1800s,

in America, archaeologists began excavating

skeletons of giants who were

seven to eight feet tall in many cases.

NARRATOR: In the 1800s,

Smithsonian archaeologists unearthed dozens

of oversized skeletons contained within the burial mounds

of the ancient Adena Indian tribe.

The highest concentration of which

were found in the Kanawha Valley of West Virginia,

an area known to researchers as the valley of the giants.

Author and researcher William Henry

is meeting up with a local Adena Indian researcher,

Jason Jarrell, to have a look

at one of these ancient earthworks.

This is the Criel Mound, and this mound was excavated

by the Smithsonian Institution

in November of 1883.

The Smithsonian sank a circular shaft

from the top of this mound

‐down through the center to the bottom. ‐Wow.

JARRELL: And that's where they found an elaborate tomb.

This structure contained 11 burials.

Ten of these burials were arranged

in a semi‐circular fashion around a central personage.

So you have ten people around a central figure.

What was significant about this central figure?

According to A. R. Sines, who assisted

in the excavation of this mound,

the central burial, when measured in the tomb,

was six‐foot‐eight and three quarters.

Now, the skull had been pulverized by the excavation,

so a complete measurement wasn't possible.

So, in all likelihood, this individual

was probably around seven feet tall.

That's a giant.

It's a gigantic humanoid.

HENRY: So we're saying the Smithsonian

came here in 1883

and discovered a giant?

That's correct. In fact, they discovered giants

in many of the mounds here in Charleston.

There were originally 50 burial mounds

‐in this valley. ‐Wow.

And I've actually got some documentation here to show you.

‐Let's see. ‐This is the manuscript

of the agent of the Smithsonian who excavated these mounds.

And this represents his day‐to‐day journal

of his excavations, including the one that's mentioned

on this page, which is measured as

seven foot, six inches in length.

HENRY: Incredible.

So wait a minute, this is a government worker...

‐Correct. Correct. ‐...who's out doing a job,

excavating a mound, and he discovers giants?

Multiple gigantic skeletons.

The ones in this valley

being between seven and eight feet tall.

That is incredible. So why don't we all know about it?

How come it's not in history books?

Well, the policy of denial of the discovery

of gigantic human skeletons actually

wasn't enacted until about 1920.

Uh, before that time period, the Smithsonian

acknowledged these giants in their own reports.

HENRY: Absolutely amazing.

For years, I've been hearing stories,

Native American legends about giants.

It appears that we've unearthed evidence,

proof of their existence, here in West Virginia.

But, for whatever reason, that proof was suppressed.

It probably has to do with the fact that

it doesn't fit with our model of human evolution.

We have to ask:

Is there an extraterrestrial connection?

CHILDRESS: You have these Biblical stories of the watchers

and the sons of God

coming to Earth, breeding with humans

to create this new race of giants,

the Nephilim.

These giant skeletons

seem to be evidence of‐of the watchers

and the Nephilim.

We have to ask ourselves

who these seven, eight‐foot giants were.

Were they somehow the vestiges of these giants of the Bible?

It's a mystery that archeologists have yet to solve.

And part of the answer may be extraterrestrial DNA

that's part of these giants.

NARRATOR: Is it possible that the remains

of a giant‐sized population were discovered

on the North American continent over 100 years ago?

If so, were these beings a variation

of Homo sapiens,

an ancient intelligent hominin,

or an otherworldly species altogether?

Perhaps further clues can be found

by examining the rarest

and most mysterious human blood type on Earth.

NARRATOR: Located between the border of Spain and France

is the Pyrenees Mountain Range.

The people that occupy this isolated region are known

as the Basque,

and they have long confounded anthropologists and historians.

The language spoken by the enclave is not related

to any other in that part of the world.

And the population also has the highest concentration

of Rh‐negative blood type in the world.

Up to 35% of Basque people have Rh‐negative blood.

And Rh‐negative blood is one of the most unusual blood types.

And it's the one blood type that is least likely

to mutate or interact with other blood types.

NARRATOR: Human blood types are grouped

into four distinct designations that include O, A, B and AB.

Additionally, there is another variance between blood types

known as the Rh‐factor, or Rhesus factor,

which is a measure

of Rhesus‐based antigens in the blood.

The name comes from a monkey from India

and other parts of Asia, which is the rhesus macaque.

And this monkey was used in experiments,

looking at blood transfusions.

How blood was received from recipients varied.

And it was discovered that

the Rhesus factor could be positive or negative.

Most humans in the world are Rhesus positive.

NARRATOR: 85% of humans in the world are Rh‐positive

and have no issues receiving blood

from positive or negative donors.

But for the Rh‐negative population,

receiving Rh‐positive blood may be fatal,

as the body will try to destroy the foreign antigens.

And for women that are Rh‐negative,

mating with a Rh‐positive partner

could be detrimental to the fetus.

If a Rhesus positive and a Rhesus negative parents

were to have an offspring,

there is a potential danger to the offspring,

because these two blood types can't interbreed, basically.

Medical intervention is needed.

It's why actually, in the past, people had to have a blood test

before they were allowed to get married.

REDFERN: The very fact that an Rh‐negative mother,

her body would actually try to kill an Rh‐positive baby

generates bizarre scenarios.

How on earth could this happen?

It suggests somewhere in our lineage

that the Rh‐negatives and the Rh‐positives are perceived

as being profoundly different.

And also, studies of Rh‐negatives suggest that

they have lower than normal blood pressure,

lower than normal pulse.

In a number of cases,

they have an extra vertebra in their back.

WILL HART: Rh‐negative is very rare.

Most of the world didn't have it

until colonization started in the 15th century.

Rh‐negative didn't exist in the Americas,

and it didn't exist in southern Africa,

it didn't exist in Asia.

It was only in Europe, so it spread out from there.

Out of Africa, that theory has it

that all human beings originated in Africa,

southern Africa, sub Sahara.

They're all Rh‐positive.

They don't have any Rh‐negative.

Where did Rh‐negative evolve, then?

NOORY: 15% of the humans have Rh‐negative blood.

Fifteen percent.

And scientists have no idea where it came from.

What they do believe is that if you have that,

you may have been evolved

from a different kind of species on this planet.

Now was that species put here, genetically altered?

Or was it just a natural formation

of the planet in its evolutionary stage?

Who knows? But the fact is that Rh‐negative people‐‐

and again, there's 15% of them on this planet‐‐

may have come from outside sources.

NARRATOR: Could the Rh‐negative blood type

offer evidence of a vastly different prehuman evolution

than what we are led to believe in our history books?

‐Might it offer indisputable proof ‐(heart beating)

of extraterrestrial intervention in the remote past?

But if so, is the experimentation

with intelligent hominin over,

or is it still taking place?

NARRATOR: A decade and a half

after Dr. David Jacobs wrote his book

proposing that aliens are experimenting on humans,

anthropologist Dr. John Hawkes publishes research suggesting

that humans have inexplicably experienced

an accelerated evolution in recent history.

Humanity entered into

a supercharged period of evolution.

If you look at DNA from a human walking around in 3,000 B. C.,

and you compare it to what we have today,

it is seven percent different.

What is this telling us?

It could be that extraterrestrials are involved

in that process, shepherding our genetic change through contact,

through genetic work that they are doing.

NOORY: Millions of people report being abducted.

They can't all be wrong.

Something is happening to these people.

And if you assume for a moment

that we may be the test tube of the universe,

where they experiment

and genetically manipulate and change things,

it's very possible that the experiment continues.

Young children are changing.

They're smarter, they're more mature,

they're growing up much faster

than we did when we were children.

What will it be like 50 years from now

or a 100 years from now is anybody's guess.

NARRATOR: Could it be‐‐

as ancient astronaut theorists suggest‐‐

that evolution is not just the result of natural selection,

but also alien manipulation?

And that humans are quickly becoming

an entirely new species,

designed to replace Homo sapiens?

HENRY: What we will begin to see in the coming decades

is the fulfillment of a plan by extraterrestrials

to ultimately transform humans into celestial beings.

The ultimate goal is to make us better suited

for traveling in space and the return to the stars.

Are we now being replaced

by a brand‐new hybridized species?

One of the things that I think about often now:

Neanderthals never knew

they were going to be replaced by Homo sapiens.

NARRATOR: Is mankind the result

of an extraterrestrial experiment?

Could isolated regions of Earth have served as laboratories

until the time when one species was chosen to continue?

And might this genetic manipulation

still be ongoing even to this day?

Perhaps it will soon be revealed

that we, too, are experimental humans,

serving as the latest link in the chain

of a directed evolution,

and being prepared for a future

alongside our alien ancestors.
