#1 - The Reptilians
Season 6 - Episode 15 - Aired 7/25/2014
The Reptilian alien is a fixture of science-fiction, from H.P. Lovecraft's tales of Valusians to the Cardassians in Star Trek, to the Visitors of the television series V. But could ancient myths about reptilian creatures provide evidence that they are more than just a pop-culture creation? Legends of serpent beings can be found on every continent. The Bible, the Quran and the ancient texts known as the Nag Hammadi codices all describe reptilian entities interacting with humans. In Central and South America people worship the feathered serpent god called Kulkukan or Quetzalcoatl. In India, the Nagas are half-human half-reptile gods who live underground in a place called Patala. And in China and Japan, many emperors claim to be the descendants of dragons. Could these stories represent real Reptilian beings that people all over the world actually encountered in the ancient past?

#3 - The Vanishings
Season 7 - Episode 11 - Aired 4/24/2015
Stories of civilizations large and small disappearing without a trace can be found throughout history and across the globe. From a previously unknown civilization in China, a vanished race of giants, to the unexplained disappearances of the Classic Maya and the Anasazi--elements of these disappearances cannot be completely explained by conventional scholars. Although these cultures have vanished from the face of the Earth, they have left behind intriguing clues--clues, some say point to an otherworldly explanation. And if entire groups have been taken off planet, might there be a connection with sites connected to mysterious vanishings of people, planes, and boats in various locations throughout the world? Could examining these disappearances lead us to not only uncover evidence of extraterrestrial intervention in our remote past, but also reveal the consequences for the future of the human race?
#4 - Aliens and Superheroes
Season 6 - Episode 19 - Aired 8/22/2014
From the beginning of recorded history, humans have told stories about beings with super-human strength, super-sonic speed, and supernatural abilities. The ancients had heroic tales about Zeus, Thor, and Hanuman while today we have superhero stories about Superman, Batman, and Spider-man. Mythologists say these epic stories resemble each other because they may have all come from a common set of oral legends created eons ago by our earliest ancestors. But might there be another, more otherworldly reason that the world's heroic myths are so similar? Is it possible, as many Ancient Astronaut Theorists contend, that these stories are actually based on extraordinary-- and possibly extraterrestrial--beings that lived on Earth in the distant past?
#5 - Hidden Pyramids
Season 7 - Episode 10 - Aired 4/17/2015
With infrared satellite technology detecting pyramids hidden underneath the sand in Egypt and airborne laser sensors discovering long lost pyramids beneath the jungles of Central America, many believe we have entered a new pyramid era--an age of discovery that will be marked by unimaginable new findings. 21st century excavations are also revealing fascinating new facts about pyramids that could potentially rewrite history. Archaeologists now believe the ancient pyramids in Peru are older than the Egyptian pyramids, and a recently surveyed megalithic site in Indonesia is now suspected to be a step pyramid built by a long lost civilization 20,000 years ago. But what can explain ancient man's apparent obsession with building pyramids? Ancient Astronaut theorists believe the world pyramid phenomena is not a coincidence, but evidence that Earth's earliest inhabitants may have had help from extraterrestrials.
#7 - Alien Evolution
Season 8 - Episode 5 - Aired 8/21/2015
Ancient Astronaut theorists have suggested that many of the divine beings depicted in cultures throughout the world are not really divine--or mythological--but instead reflect extraterrestrial visitations that our ancestors did not understand. If true, what can account for all the different types of beings that are depicted, from anthropomorphic birds and reptiles, to gods with blue skin to multi-limbed humanoids? Might there have been numerous alien species inhabiting Earth? Could the accounts given by modern day alien abductees be evidence that these otherworldly entities continue to visit Earth to this day? And is it possible that they all have a common ancestor? In 1928, archaeologist Julio Tello discovered the Paracas skulls of Peru--elongated heads with cranial volumes at least 25% larger than the largest known human skulls. Some believe that these remains are of extraterrestrial origin.

Crop circles have been making modern headlines since the 1960's, but their history can be traced back hundreds--if not thousands of years. The designs themselves often contain encrypted messages and complex mathematical, geometric, and astronomical equations that perplex our top mathematicians and scientists. Ancient Astronaut Theorist, Giorgio Tsoukalos travels to England to meet with researchers and scientists to investigate the phenomenon both on the ground and in the lab to find out what we haven't been told.

India's Sanskrit texts are filled with incredible stories about advanced technology in the ancient world. Highly complex building techniques, brain surgery, flying crafts, and even nuclear physics are described with uncanny accuracy. Hindu scholars attribute this knowledge to a time when "gods" walked among men. Might this period of time actually be referring to an age when extraterrestrials inhabited the planet? Giorgio A. Tsoukalos travels to India to further explore the Sanskrit texts, as well as the structures and technology that have stood the test of time. From a temple that inexplicably survived a major earthquake to evidence of ancient brain surgery and instructions for advanced flying machines, Giorgio studies the sacred knowledge that is said to have come directly from the voices of the gods.

#19 - The Alien Frequency
Season 12 - Episode 8 - Aired 6/16/2017
The use of mantras and chanting to connect with a higher plane has existed in cultures all over the world dating back thousands of years, but why would people who had no contact with each other all subscribe to this practice? Could there be certain frequencies that connect us with greater--perhaps extraterrestrial--forces? Researchers have found that dozens of megalithic sites stretching across the globe--like the prehistoric Newgrange monument in Ireland, the chiseled labyrinths underneath the island of Malta, and the giant temple complex of Angkor Wat in Cambodia--were all designed to emanate the exact same frequency. The planets in our solar system each give off a distinct sound, and certain places on Earth, like Taos, New Mexico, have been found to produce a hum from an unknown source. Might the best evidence of alien intervention on Earth be found not with our eyes... but with our ears?

#23 - Creatures of the Deep
Season 8 - Episode 7 - Aired 9/4/2015
In August of 2014, Russian cosmonauts aboard the International Space Station discovered something incredibly unexpected covering parts of the windows--living sea plankton. If sea life can thrive in space, might the reverse be true as well? Might there be alien life forms that inhabit our seas? Throughout history, there have been tales of strange creatures hiding in Earth's waters. While many discount stories of sea monsters as purely mythological, it is estimated that Earth's oceans are home to between 700,000 to one million species--and shockingly, two-thirds of those species still remain unknown. Considering the recent discovery that some sea life can survive in outer space, is it possible that tales of giant creatures like the Kraken and The Loch Ness Monster are evidence of extraterrestrial entities taking refuge beneath the seas?
