S20 E13 - The Whistleblowers
For decades, incredible claims have been made about an extraterrestrial presence on Earth, and the government has gone to great lengths to discredit them.
Massive stone structures that reach to the heavens... strange, giant figures buried deep in the Earth... and energy emitting spheres connected around the globe... What compelled ancient man to move colossal stones, in some cases weighing thousands of pounds, and to build remarkably similar stone monuments all around the world? From the jungles of Costa Rica to England's rural countryside, ancient people achieved extraordinary feats of construction without advanced tools or technology. Is it possible that extraterrestrials instructed the ancients to build these complex structures? Or were our ancestors driven to create these monoliths in order to reconnect with celestial travelers who once walked the Earth? Could ancient monoliths hold advanced, extraterrestrial powers we have yet to realize? And if so, just what will happen when we unlock the mystery of the monoliths?

S5 E7 - Prophets and Prophecies
They were the messengers of divine knowledge and seers who shared visions of the future. For thousands of years, human civilization has been guided by the words and deeds of ancient prophets, but just who--or what--were these prophets communicating with? Might the experiences of history's prophets be evidence of communication with a heavenly source--or were seers like Elijah and Joseph Smith actually communicating with extraterrestrial overlords? And if so, are there similar prophets at work today?

S11 E4 - The New Evidence
Millions of people around the world believe we have been visited in the past by extraterrestrial beings. What if it were true? This is the question Ancient Astronaut theorists have posed since Erich von Daniken's Chariots of the Gods was first published in 1968; examining scientific, archaeological, astronomical, and historical evidence to find the answer. In recent years, more new evidence has been revealed than ever before that suggests there was extraterrestrial intervention on Earth in the distant past. Satellite images have exposed geoglyphs resembling Nazca lines in Kazakhstan. Ground penetrating radar has detected remnants of ancient technology in Machu Picchu. And thermal scanning has uncovered hidden chambers behind King Tut's tomb that may hold the remains of extraterrestrial beings. Could we be at the tipping point where the overwhelming evidence outweighs any last shred of doubt?

S10 E4 - Dark Forces
Good and Evil. Light and Dark. God and Satan. In nearly every culture there are stories of opposing forces at work here on Earth--forces of a supernatural or otherworldly nature. Could these forces really exist? And if so, what is the true nature of the dark forces? Throughout history, there have been individuals accused of being in league with agents of darkness. The infamous mad monk Rasputin believed he served as a conduit for an otherworldly realm, the Nazi SS were said to have tapped into dark powers through ancient symbols, and famed occultist Aleister Crowley claimed to have summoned a non-human entity through the use of dark magic. Is it possible the entities these men claimed to be in touch with were, in fact, extraterrestrials? And might humans serve as the pawns in a cosmic battle between the forces of light and dark?

S12 E7 - City of the Gods
The ancient site of Teotihuacan in central Mexico--which the Aztecs called the "City of the Gods"--is one of the world's greatest mysteries. To this day, no one knows who built the metropolis or what happened to its occupants, but based on evidence that has recently been unearthed, Ancient Astronaut theorists suggest it was once home to a highly advanced, perhaps extraterrestrial, civilization. The many structures that still stand in Teotihuacan appear to be encoded with advanced mathematical and cosmic principles, and the layout precisely mirrors the positions of the planets in our solar system. Modern excavations at the site have unearthed discoveries of liquid mercury, walls lined with mica, and strange golden-spheres containing unknown substances--all of which are out of place in the ancient world. Could these artifacts be the remnants of an alien society? Perhaps even an extraterrestrial spaceport?
