Season 6 - Episode 11 - Aired 3/14/2014

Demonic seduction… hybrid offspring… and strange abductions. In cultures throughout the world, there are tales of intimate encounters with otherworldly beings. But could these stories be more than just mythology? Scientific deconstruction of human genetic makeup has revealed that our origins are not what we once believed. Biologists have determined that early humans mated with several other species of intelligent hominids. Neanderthals, Denisovans, and a third–as of yet unidentified–species may also be represented in our DNA. Is it possible that tales spanning from fallen angels to Greek gods, medieval incubus and succubus to today's extraterrestrial sexual encounters are all one in the same? And if so, is it all part of a greater agenda? Might examining these experiences provide not only evidence of extraterrestrial sexual intervention in the remote past, but also reveal the true nature of mankind's origins?

Season 5 - Episode 3 - Aired 2/15/2013

Erich von Daniken's landmark book, Chariots of the Gods, brought attention to the mysterious phenomena of the Nazca Lines. Hundreds of gigantic lines, some in the shape of animals, geometric patterns and even an alien-like being, extend for miles throughout a remote Peruvian desert. Scholars are divided as to who built them, and why. Some Ancient Astronaut theorists believe that the massive markings have an extraterrestrial connection, and perhaps the ancient people of the region created these gigantic figures in tribute to the gods who visited them. And with one of the largest deposits of nitrates in the world--a key ingredient in rocket fuel and weaponry--could Nazca have been a mining operation for advanced beings in the distant past?
