Ancient Aliens - The Ultimate Guide to UFOs

Episode Date: August 27, 2026

UFO witnesses have reported a wide variety of objects in Earth’s skies–and not only in modern times, but for centuries. What might we learn from examining their shapes, sizes, and the way they maneuver?See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Flying discs making impossible maneuvers. The gravitational forces inside these objects would crush any living individual. Triangular craft appearing out of thin air. He actually was 100 feet away from that flying triangle and could see through it and the stars above. Enormous cylindrical objects filling the sky. It had the radar return equivalent to 10 aircraft carriers. aircraft carriers, except this was up in the air. UFO witnesses have reported objects of all shapes and sizes.

Could they offer important clues about other intelligent life in our galaxy? Might there be links between the shapes of UFOs and the different types of entities that are sometimes reported? It's very conceivable. They're coming from different planetary systems throughout the universe. There is a doorway in the universe. Beyond it is the promise of truth. It demands we question everything we have ever been taught.

The evidence is all around us. The future is right before our eyes. We are not alone. We have never been alone. Nuremberg, Germany. At dawn on April 14, 1561, The citizens of this Bavarian city at the center of Europe awake to a commotion in the sky,

unlike anything they have ever experienced before. William Henry is an author and investigative mythologist. People went outside and they saw what they described as a celestial battle. The witnesses observed seeing hundreds of these strange-shaped objects. What were these strange shapes that they were describing? The aerial scene illustrated in a contemporary woodcut is described in the accompanying text as a very frightful spectacle. Strange objects seem to launch projectiles as onlookers below watch in amazement. Here is agent astronaut theorist Giorgio Suclos.

This was actually witnessed by thousands of people. Had it been a meteor, shower, or something like this, then the report, reports would have been, okay, this happened before because we've seen this before, but that was new. The witnesses, they wouldn't have had a conception of some kind of a mechanical spacecraft, but that seems to be exactly what they were describing. And this has to be one of the greatest mass sightings of a UFO phenomenon in all of recorded history. Incredibly, a very similar incident was reported in Basel, Switzerland five years later, and was illustrated in in a woodcut that still exists to this day.

Is it possible that these two events, witnessed by thousands, represent the first mass UFO sightings on record? The UFO phenomenon is not modern. It goes back as far as we can remember, because we have accounts of lights and craft not only in modern times, but also in ancient times. Ancient astronaut theorists find it remarkable that the depictions of these 16th century sightings include every shape of craft that has been reported by UFO witnesses in modern times.

But it also poses an important question. If these are, in fact, representations of alien vehicles, what could explain all the different shapes? Bill Burns, PhD, is the co-author of The Day After Roswell. So it well might be that different types of UFOs are tasked for different purposes. There are scout ships. There are ships that only orbit. There are motherships.

They're all tasked for different purposes. George Neury is the host of Coast to Coast AM. If you look at our planet today, almost every country has some kind of flying machine that is different from what we have. I think the same thing as the case with extraterrestrials. Let's assume there's 10 different ET races within our Milky Way galaxy. Each one could have a different shape to its craft because that's just the way they created it. And I think that's very conceivable. When we see cigar-shaped UFOs, triangular-shaped UFOs, round UFOs,

they're coming from different planetary systems throughout the universe. Could the various shapes that have been witnessed in the sky for hundreds of years all represent extraterrestrial crafts, as ancient astronaut theorist suggest? And if so, with a more advanced technological frame of reference, might modern humans be able to gain insight about who or what is visiting Earth by examining these shapes? Nick Pope is a former member of the British Ministry of Defense. Are there conclusions that you can make about the different shapes of UFOs that are reported? Might there be links even between the shapes of UFOs and the different types of entities that are sometimes reported? In modern times, the most commonly reported UFO shape is the iconic flying saucer. The term was coined in 1947.

After pilot Kenneth Arnold spotted a number of flying saucer, objects near Mount Rainier in Washington traveling at incredible speeds. David Childress is the author of Technology of the Gods. He described them as skipping through the air like a saucer, he said. And this is really where the term a flying saucer arrives in English language is from Kenneth Arnold's description. With more saucer-shaped objects reported. around the globe, the United States government began to investigate reports of UFO activity.

Amy Shira Title, Ph.D., is an author and spaceflight historian. It wasn't just the United States that was interested in potential UFOs in the mid-century. Canada, France, the Soviet Union, the United Kingdom, and Brazil all had various programs to determine whether or not it was a threat for humans. Could it be that reports of flying saucers caught the attention of world governments because they have a shape unlike any man-made craft. Uphologists suggest that these sightings triggered a competition by world powers to manufacture their own craft based on this exotic design.

A design that many presumed must have some unknown but inherent advantage for flight. There's no question that historically governments have attempted to recreate the shape of UFO craft that have been seen, spotted, or crashed. In the 1950s, the Pentagon funded a prototype for a disc-shaped craft. This once-classified project yielded a nearly three-ton flying saucer, the VZ9 Avrocar. The Avrocar was one attempt to develop a flying saucer, and it was a VTAL design, a vertical takeoff and landing. It was designed by a Canadian company Avro for the U.S. military. The U.S. Air Force wanted it to be a supersonic interceptor and fighter,

and the U.S. Army wanted it to be something stealthy that could hover above the ground in silence and detect radar. Avro engineers thought that this big circular wing might be the design that could meet both requirements. In 1959, after years of top secret development, this flying saucer prototype was finally put to the test. In preparation for the final contractual demonstration, a representative course was selected where the vehicle could demonstrate its capability while remaining in view of the observers. It turned out that the cushion of air under that wing became extremely unstable just a few feet off the ground. There was one model built and some wind tunnel test done, but ultimately it was deemed completely aerodynamically unstable. While the Avrocar failed, in 2019,

In 2019, Romanian engineer Rosvon Sabi, and aerodynamicist Iosov Tapasu, unveiled their answer to the flying saucer problem. The all-directional flying saucer, or Adipho, demonstrates precision maneuverability and outperforms all previously known flying saucers constructed by humans. The Atifo design looks really interesting. It looks like a highly maneuverable flying saucer design, but it's small. and it's a drone. It would be interesting to see how the engineering works with a full-size design,

because engineering is very difficult and usually doesn't scale up very cleanly. This saucer utilizes four ducted fans, like a quadcopter drone, and it is also equipped with jets for added thrust and lateral nozzles that provide side-to-side mobility and rotation. The saucer only currently exists as a miniature prototype, but its creators plan to pursue a full-sized manned version capable of hypersonic speed. If successful, will we have finally achieved the same technology as extraterrestrial space travelers?

Or could recent events reveal that they are still light years ahead of us? Ancient astronaut theorists have speculated that one reason extraterrestrials might have designed disc-shaped craft is so that they can instantly change direction and at tremendous speeds. We can learn a lot from modern UFO reports. These disc-shaped craft are able to make sudden turns, turning at high speeds in any direction. Richard Dolan is the author of UFOs and the National Security State. When you're thinking in terms of aerodynamics, shape, should matter a great deal.

But what if aerodynamics is not really relevant? What if these objects are able to employ a different kind of a science that makes aerodynamics irrelevant? One of the concepts here is that these circular or disk-shaped craft are using anti-gravity for propulsion. They're not rockets. They're anti-gravity. They're generating their own gravitational field.

which would likely be a spherical field around the craft. Is it possible that reports of disc-shaped objects changing direction at incredible speeds, some of which have even been captured on video, are alien craft with anti-gravity technology. While there is no hard evidence that anti-gravity aircraft do exist, there has been much speculation as to how such craft might function. One theory is that they could be, in part, driven by centrifugal force, the force that is felt by a rotating or spinning object. Michael Masters, Ph.D., is a professor of anthropology at Montana Tech University.

The shape of these craft is consistent with these different models of rotation around a central axis, involving something with high mass and high energy. Ancient astronaut theorists point out that such spinning wheel-like, machines bear an eerie resemblance to one of the most famous and enigmatic stories from the Hebrew Bible. The story of Ezekiel's wheel. When you have these ideas that are currently proposed of these gigantic wheels in the sky that spin on their own axis in order to create artificial gravity. I might as well be reading Ezekiel. It's very similar.

In the Bible's book of Ezekiel, the prophet described. describes a fiery chariot drawn by four living creatures. Each creature is flanked by a metallic object, a wheel within a wheel, that Ezekiel observes as it descends making a tremendous amount of noise. It is 1968 book, Chariots of the Gods. Ancient Astronaut Theory pioneer Eric von Danikin proposed that what was actually being described in Ezekiel was a spaceship. engineer Joseph Blumrich was determined to debunk this controversial theory, but after

painstaking research, the author was shocked to find himself agreeing with Eric von Danikin. In 1974, he published his own book supporting Eric's theory entitled, The Spaceships of Ezekiel. Blumrich reads Ezekiel and he has an epiphany because what is he describing? He is describing a wheel up in space. Blumrick says, by gosh, Eric is right. And so he conceived what Ezekiel may have described in that ancient biblical text. Travis Taylor, Ph.D., is an aerospace engineer.

Ezekiel describes that the outside of the wheel doesn't spin. The inside of the wheel spins. So he's telling us that's the engines. None of this necessarily has to be magic. This could all be technology. Perhaps what the wheel actually signifies is the secret of the gods. The secret of their extraterrestrial spacecraft and how humans might be able to reverse engineer that wheel and ultimately make their own craft. Is it possible that a story from the Bible's Old Testament describes the propulsion system of an extraterrestrial spacecraft?

Well, Ezekiel's description of wheels within wheels may represent a primitive intent. interpretation of highly advanced technology, one band claims to have firsthand knowledge that anti-gravity craft do exist. Area 51 whistleblower Bob Lazard. Investigative journalist George Knapp was the first to interview him in 1989 about the notorious military base that has long been rumored to be hiding alien technology. He told this incredible story that he'd been working at this facility called S4. south of Groom Lake, that they had a hangar hidden in the desert to make it look like it was actually a part of the desert terrain.

And inside those hangars were nine flying saucers. Here is investigative filmmaker, Jeremy Corbell. So Bob Azar was tasked at Area S4, a subsite of Area 51, to reverse engineer the power and propulsion of what we know as a flying saucer. All of the nine craft that Lizar was able to see with his, eyes were said to have worked on the same gravity system. Bob Lazar said the craft would turn belly first and the gravity wave amplifiers would all point to the place in time space where you want to go.

We're talking about a gravity propelled craft. We're talking about something that you don't have any effect of the inertia or momentum. It's just instantaneously, boom, boom, boom, boom, one place than the next. Element 115 was what we would call the fuel, what provided the power. power for the reactor to work.

Element 115 affects gravity. Element 115 produces its own gravitational energy. The resulting gravity wave creates a distortion in front of it, allowing the craft to slide forward. And that's how it perceived. Could Bob Lazars extraordinary claims about the flying saucers he allegedly worked on at S4, along with video evidence of UFOs, reveal that there

There are alien aircraft in our skies equipped with anti-gravity technology. Michi Okaku, PhD, is the author of The Future of Humanity. Anti-gravity is not possible with the known laws of physics. So when I talk to my physicist friends about flying saucers and stuff like that, I get the giggle factor. They start to giggle, their eyes roll up into the heavens because you see, I think they make a mistake. They assume that the aliens are maybe a hundred years more advanced than us, in which case, yeah, it is impossible for a civilization 100 years from us to reach us from

the stars. But what if? What if they are a million years ahead of us? New laws of physics are going to open up once you have a civilization that is a million years more advanced than us. A million years is nothing but a blink of an eye compared to the age of the universe. Many UFO researchers believe the flying saucer is designed to take advantage of an anti-gravity propulsion system and is the optimal shape for maneuvering quickly in any direction. But what could explain the numerous other types of unidentified craft that have been reported? Perhaps further clues can be found by examining a UFO shape that more closely resembles man-made aircraft, The Flying Triangle, Henderson, Nevada, March 13th, 1997. At 6.55 p.m., local police

receive a report of a massive V-shaped object traveling southeast across the night sky. Over the next three hours, the craft is witnessed by thousands of people as it journeys down through Arizona and into Sonora, Mexico. With most of the reports, coming from Phoenix, as well as photographs and video footage, the incident becomes known as the Phoenix lights. The entire city of Phoenix was able to see this half a mile long display of lights over the city in a very, very distinctive pattern. It was a triangular-shaped object, seemed very reliably by quite a large number of witnesses.

Who's our best witness to that? The best one, Governor Fife Symington of Arizona. As a pilot and a former Air Force officer, I can definitively say that this craft did not resemble any manmade object that I'd ever seen. And says, yeah, I really did see the UFO. And he describes it. He actually was maybe a hundred feet away from that flying triangle and could see through it and the stars above.

Governor Symington was a qualified pilot and in the Air Force Reserve as well. I think he knew what he was seeing. The governor of Arizona described a strange triangular UFO that appeared translucent, camouflaging itself admits the starfield above. This incredible mass UFO sighting made the front page of USA Today. And then three years later, it happened again. St. Clair County, Illinois, January 5, 2000. At 4 a.m., three large triangular objects are seen by multiple witnesses, including police officers, flying silently in the night sky.

I looked up in the sky and observed this huge arrow-shaped, triangular-shaped object. They are observed for at least two hours, and over more than one town. This is military aerospace historian Mike Schrat. This is known as the famous Southern Illinois Flying Triangle. We have about four different police officers. What they described seeing are three distinct arrowhead shape craft. Officer Craig Stevens was directly below one of these triangles and he said that it was trying to cloak or camouflage itself against the night sky and was projecting the star field above

it on the bottom surface, allowing it to effectively blend in with its background. The ability of triangular-shaped objects to hide in plain sight reminds many observers of modern stealth technology. Developed by the U.S. military in the 1970s and 80s, stealth technology allows triangular-shaped aircraft to appear invisible to radar, sonar, and other detection methods. Michael Dennan, PhD, is a physicist at the University of California, Irvine. To make something invisible to radar, all you have to do is make sure that the radar doesn't reflect back to the receiver. So you send out a radio signal, you bounce it off the plane, you get the signal back, and now you detect it by radar. This all comes down to mostly the shape of the planes, though it's a little bit the material too, but it's predominantly the shape.

You want it shaped in a way so that the radar either scatters in random, directions or literally just bounces off in a completely opposite way. Could the masking technology attributed to the Illinois Flying Triangle and to the craft observed during the Phoenix Lights incident be a highly advanced version of this same principle, some kind of alien stealth? Michael Sala is the founder of ExoPolitics Institute. Stealth technology has been developed to hide some of these spacecraft, to simulate an environment

behind the craft, so this can be done in a way to make a craft disappear. Ancient astronaut theorists suggest that the triangular shape employed by the Phoenix and Illinois craft, and now by the US military, has populated the skies since ancient times. As proof, they point to evidence of triangular ET surveillance craft in the ancient world in the form of a symbol called the all-seeing eye. Bruce Fenton is the author of Exogenesis, Hybrid Humans. The triangle with an eye in the center is commonly used as a depiction of God, particularly in ancient Egypt.

But we also see this in the Catholic faith. Masonic circles, we see it on the US dollar bill, and indeed, you know, in some of the ancient artwork. Now, could it be because the craft, which we have reported in the skies, look like a triangle with a light in the center, rather like an eye looking down on us. Some believe that the eerie similarity between triangle-shaped UFOs and the U.S. military stealth aircraft is no mere coincidence. Logan Nye is a former public affairs specialist with the U.S. Army. Stealth technology traces its roots back to a single series of papers written by a Soviet

physicist. This Soviet physicist realized radar doesn't see the way that the human eye sees. And so if you change the shape or composition of an object, that'll affect how it shows up on radar. American engineers, when they learned about this, went back and started experimenting with how to apply that to an aircraft. And a lot of their test work was done at Area 51 and Groom Lake,

which of course has just made it a mecca for conspiracy theorists. And then later, people started to wonder if there were actually alien technologies there. Area 51, the US Air Force installed in Nevada long suspected to be hiding alien technology? Is it possible that the conspiracy theorists are right? And that the stealth bomber is the result of reverse engineering

extraterrestrial craft. A lot of people say this is actually something we've developed, back-engineered from extraterrestrial technology. This is absolutely quantum leap technology. I think there's no question. I think there's no question that we have reversed engineered or have looked at the shapes of these craft and have tried to create it for ourselves. Look at some of the new stealth jets that are coming out right now. They're amazingly close to what we saw 20 years ago from UFO reports.

UFOs shaped like triangles and saucers reported in the skies for centuries can potentially teach mankind a lot about the alien entities who may be piloting them. But are these craft the actual motherships that carried alien visitors across the vast distances of interstellar space? Or are they simply smaller probes designed to enter and navigate the Earth's unique atmosphere? And if so, did these probes arrive here on board much larger vessels? Vessels with entirely different shapes and with sizes that would stagger the human imagination. Antofagasta Chile, December 1978.

Two Chilean pilots are conducting a training mission at 35,000 feet when they detect something highly unexpected, a massive cigar-shaped object. They encountered visually and on their airborne radar, an absolutely enormous object in the sky. In fact, two separate ground-based radars tracked this object. We are told that it had the radar return equivalent to 10 aircraft carriers, except this wasn't floating on the water. This was up in the air.

One aircraft carrier alone is a massive vessel that stretches to about 1,000 feet in length and towers 30 stories above the water. Some can hold upwards of 75 aircraft and can accommodate over 4,000 personnel. I don't know what could be as large as 10 aircraft carriers up in the sky, but this was quite immense. As the pilots approached this object, and you have to imagine they had to be somewhat terrified. One of them described it as a very elongated object swathed in smoke. As they got to a certain distance, this thing instantly. accelerated and was just gone. Based on the descriptions of the two pilots, many researchers believe this to be the largest

UFO ever reported. And in fact, many of the larger UFOs on record have a similarly cylindrical shape. The cylindrical craft is a typical UFO shape, one that we see a lot of. And in fact, the very first photo of a UFO is of a huge cylindrical. craft over Mount Washington and New Hampshire, taken in 1870 right at the very beginning of photography. On March 25, 1989, an infrared image was taken by an unmanned Soviet Martian probe called Phobos 2 that was beamed back to Earth. It captured a massive 15-mile-long cylinder-shaped UFO approaching one of the two small moons of Mars. Mysteriously, moments after the photo

was taken, the Soviet probe disappeared. Paul Stonehill is the author of the Soviet UFO files. JPL was in the know. They kept watching, I think, every second of the mission. They knew when the probe disappeared and then was destroyed. So I think there is something on that moonlet that is capable of destroying spacecrafts from Earth, and they know it. Officially, the loss of the Phobos 2 probe was blamed on a malfunction of the onboard computer,

but no explanation was ever provided for the enormous cylindrical object that was captured by its camera. Could it be that the cylindrical craft was in fact a mother ship from a distant star system? In 2017, another massive cigar-shaped object was spotted traveling towards Earth, and this time, astronomers made international headlines, when they announced that this strange intruder had indeed arrived from a distant star, the first interstellar object ever proven to have entered Earth's solar system. In October of 2017, there was the very strange object. Very cylindrical and long called Umuamua, which was, I believe, sent to our solar system.

We've had some space stories which have been pretty eye-opening, like Omuamua, where we've had open speculation about how this thing might be an interstellar spacecraft. Is it possible that massive cigar-shaped objects like Omoa-Mua, the image captured by the Phobos II probe, and the UFO witnessed by pilots in Chile, represent alien craft? Ancient astronaut theorists say, yes, and believe that these craft serve a specific purpose, one that can be found by examining Hindu texts that date back thousands of years.

Deepak Shimkata is a professor of Hindu studies at Claremount School of Theology. In Hindu texts such as the Ramahina or the Mahavarata, the Bimana is primarily a flying ship that God used to travel back and forth between spaces in heaven, from one planet to another planet, from one universe to another universe, and also come to Earth. The Vamana text describe at least five different types of Vamanas that have different shapes.

Some Vamonnas are tubular, cylindrical craft and can carry large amounts of people in them. All these Vedic texts speak of a time when three cities were orbiting Earth. And from these cities, smaller vehicles were used in order to reach the realm of the Earth. Even extraterrestrials with their advanced technology would have to arrive with a larger mothership orbiting the Earth

and from that mothership, smaller vehicles will enter the Earth's atmosphere going back and forth. And this is why we have to be. have these stories of vehicles with which to reach the larger palaces up in the sky. Personally, I also think that whatever it is seen today with the modern UFO phenomenon, the big craft is out there. The so-called cigar shape could be the larger vehicles which were orbiting the Earth. Could it be that reports of cigar-shaped UFOs are really sightings of alien motherships?

Are these the interstellar barges that transport both extraterrestrials and their fleet of aircraft across vast distances of space? Ancient astronaut theorists say yes, and suggest that by more closely examining the behavior of these variously shaped UFOs, we may learn something about the beings that pilot them, or if they're even piloted at all. Jerusalem, Israel, January 28th, 2011. An unidentified glowing object descends from the darkness and hovers above the Temple Mount. A holy sight revered in Judaism, Christianity, and Islam for thousands of years. The 2011 UFO sighting over the Temple Mount is absolutely fascinating. You see this light slowly descend.

Rabbi Ariel Barr Sadok is the founder of the Kosher Torah School. That happened to Jerusalem on a Friday night on a Sabbath. We have too many witnesses from too many sources that can prove that this actually happened. And this is what happened. There was a light that appeared over the Temple Mount. And it was just there. A glowing globe. And it was picked up on film by multiple different people

from multiple different forms. And suddenly, it accelerates vertically upwards at immense speed, and you can hear some of the passers by gasping in shock and amazement. If this is genuine, it's of extreme significance. The Jerusalem UFO exhibited astounding acceleration and maneuverability, but it's hardly alone. On September 18, 2013, in Wittenberg, Germany,

a witness records an unidentified triangular object that is also capable of accelerating at impossible speed. And in December 2017, infrared footage goes public, showing a tick-tac-shaped object off the coast of California that radio operators track at 3,600 miles an hour. The fastest man-made aircraft, the Lockheed SR-71 Blackbird, tops out at just over 2,000 miles an hour. When you're looking at all of the different UFO reports over the many years

with all of the shapes and types of performance that are noted, flying saucer-shaped objects, spherical-shaped objects, cigar-shaped objects, all of these have shown. incredible ability to accelerate, all of them. For UFO researchers, the most compelling accounts are those in which the object maneuvers in such a way that it not only exceeds the abilities of any man-made aircraft, but would actually kill a human pilot.

So when you think about things moving and having very high accelerations in G-forces, we know that most things based on organic matter. that are living are going to be unlikely to survive those forces. There's only so many G forces the human body can take before you run into a lot of medical problems. So with some of these fast-moving objects people have seen, move in ways that would kill a pilot. Are extraterrestrial crafts flown by incredibly resilient beings

capable of withstanding forces that would otherwise kill a human pilot? There was this DIA report, Defense Intelligence, about these different types of alien creatures, one of which is fascinating. It's called transmorphic. And what that means is these creatures aren't corporeal the way we are. They're energy beings, they're light beings.

Some believe that these objects that fly at bone-crushing speeds could be piloted by beings that are not bound to a rigid, physical form. But others suggest a more likely explanation is that the craft don't have pilots inside them at all. These are hypersonic devices. They can also zigzag, and the amount of zigzagging is so great

that the gravitational forces inside these objects as they jerk through space and time would crush any living individual. In my opinion, whatever these objects are, they're guided either by remote control or by an autonomous cybernetic system. Now, when we look at the cutting edge of science today, we realize that space exploration probably won't be carried out by living people, but instead by robot craft.

And this is already happening. You know, our explorations of Mars and of the solar system involve robot craft, not human beings. Could it be that an advanced extraterrestrial civilization would have gone down the same route and sent living AI craft to explore our planet? If aircraft of all shapes and sizes have been sent to Earth from alien motherships, as ancient astronaut theorists suggest, could they be robotic drones that are remotely controlled from far above the planet?

Or is it even possible that the craft possess highly advanced artificial intelligence and fly autonomously? And if there are no pilots to accommodate, could this suggest that these crafts are capable of more than we ever imagined. Pasadena, California, September 25th, 2019. A robotics team at NASA's Jet Propulsion Laboratory announces a new prototype robotic system that will one day be able to explore the most inaccessible areas

of distant worlds. Many robots that can combine and transform to roll, fly, float, and swim in any environment. NASA is calling them shape-shifters. NASA is looking at shapeshifting robots to explore other moons and planets, like Saturn's Moon Titan. It's looking at having a shapeshifting robot as part of a probe that could adapt to the different environment on Titan's surface,

flying through the air, exploring the ground, and even going into the methane and ethane seas. The individual components are kind of self-contained mini-robots, that work together as a collective and create new and interesting shapes depending on what you need to go through. It's been noted with a number of UFOs that have been observed. Sometimes they change shape. At one point, they look like a triangle,

and then they look like a disk. Another technology that NASA is developing for deep space travel is self-replicating robots. Artificially intelligent machines that are able to use the resources found on celestial bodies to create more of themselves, colonized planets, and even evolve into more sophisticated machines. This has led some to speculate that the UFOs witnessed in our skies are not dependent on external control at all.

If you're an alien civilization looking at the galaxy with 100 billion stars, you may not want to send Captain Kirk hopping one by one. It would send self-replicating robots. They would land on the planet, make hundreds of carbon copies of themselves that would launch off and colonize other moons. From one robot, you would get 100, then a thousand, then a million, billion.

While we are certainly dealing with technological craft in certain instances, it's also true that we are finding evidence for conscious entities that are spacecraft. From an ancient Egyptian civilization, Egyptian symbol to a 16th century Swiss illustration and modern day footage captured by military aircraft. Is there overwhelming evidence that UFOs and extraterrestrial craft not only exist, but they have been present on planet Earth for thousands of years? Flying discs with exotic propulsion systems.

Stealth aircraft that can appear and disappear at will. and massive motherships carrying space travelers from light years away. As new technologies allow us to capture more and more unidentified flying objects, perhaps we will soon discover that their numbers are far greater than we ever imagined. And it is not that they are in our airspace, but that we are in theirs.
