The Other Earth-S8/E6

Billions of dollars have been spent in our quest to find an “other Earth.” Since the launch of the Kepler Telescope in 2009, scientists have identified thousands of planets capable of supporting life. Is it possible that this discovery finally answers the age-old question: “Are we alone in the universe?” Could it be that just as we seek out other habitable planets, advanced extraterrestrials from distant galaxies did the same with Earth in the remote past? Throughout world mythologies, there are tales of beings from the stars coming down to Earth. The Dogon tribe in Africa believes their gods came from the Sirius star system. The Maya associated their gods with the Pleiades star cluster. And according to the Hopi tradition, life itself was seeded by celestial beings. Ancient Astronaut theorists propose that not only has our planet been visited by extraterrestrials, but that they are responsible for our very existence.

The Alien Evolution-S8/E5

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.

Dark Forces-S8/E4

Possessed by demons...The dark side needs physical bodies to act and exist in. Tempted by evil...Many people desire things so badly that they're willing to forfeit their immortal souls. And enlisted to the dark side...They understood that they were serving darkness. If there is good that exists in the world must there also be evil? Are there negative energies that permeate the cosmos? And if so, might the true source of these dark forces be extraterrestrial beings?

Aliens and Robots-S8/E3

Incredible strength… Superior intelligence… And even the ability to reproduce. In the 21st century, robots are being programmed to do everything from performing surgery on humans–to exploring other planets. And humanoid robots are rapidly reaching a level of sophistication that was thought to exist only in science fiction. But what are the implications of creating robots that are increasingly intelligent and independent? Is the obsession with creating counterfeit humans really pointing the way to mankind's future… or to its past? Greek stories dating to 2000 B.C. tell of the god Hephaestus creating robots to build weapons, as well as the bronze giant Talos. In Egypt, the Pyramid Texts say that the god Osiris was dismembered, then reassembled and brought back to life just like a machine. If sophisticated robots really did exist in the ancient world–what function did they serve? Who built them? And what happened to them?
