Season 6

Across ancient civilizations, the world's mountains were viewed as the sacred home to all-powerful gods. Why would so many different cultures share this belief that mountains had a connection to otherworldly beings? The Greeks believed their most powerful gods, the Olympians, waged an epic war for control of the universe from Mt. Olympus. Ruins of a 4000-year-old observatory discovered on a mountain in Macedonia reveal that the ancients tracked celestial movements from on high with remarkable precision. And in Peru, the descendants of the Incans continue an ancient pilgrimage tradition in order to commune with mountain spirits known as Apu. Could these gods have been extraterrestrials? Did they use remote mountain peaks to interact with early man? Might this explain why humans have been drawn to mountains for thousands of years?

The Ark of the Covenant is one of the most sought after religious relics of all times and far more than just a box that contained the Ten Commandments. The biblical stories surrounding the Ark speak of a device with divine powers that was able to produce food, take down stonewalls, kill those that come in contact with it, and provide direct communication to God. Are these stories mere myth? Or did the Ark of the Covenant possess extraordinary powers? What happened to this incredible relic? Could it still be hidden? Are we getting close to a rediscovery--and reactivation--of the Ark? And if so, will the Ark of the Covenant reveal a long, lost connection to our extraterrestrial past?

Legends of lost and mysterious islands, advanced civilizations and Eden-like paradises have been told by sailors throughout human history. Is it possible these stories are more than just the myths of imaginative seafarers? Might evidence of our Ancient Alien origins be found by exploring the world's most remote islands--strategic spots where extraterrestrials may have once made their earthly homes... and possibly still visit today? Unidentified submersible objects going at lightning speed... strange crafts coming out of water near remote volcanic islands... and mystifying megalithic ruins in the middle of the ocean. Is it possible UFO activity could be hidden deep underwater and off the coasts of islands? Could this explain why so many islands around the world have stories of unexplained sightings of objects both overhead and beneath the sea going back centuries?

Sacred bones... Golden hats... And fragments of sacred objects thought to possess healing properties. All around the world, archaeologists have uncovered mysterious relics revered by ancient cultures for thousands of years. Now on display in museums, temples and churches, millions of people travel great distances just to be in their presence. What is it about these ancient objects that draws people to them? Could the truth of mankind's origins be found in the fabric, metal, stone and bones of our distant past? And could these mysterious relics really provide us with the ability to access divine or otherworldly power?

Powerful monarchs ruling by divine right. Centuries-old dynasties amassing enormous wealth. And legendary leaders wielding powerful weapons of mass destruction. Is it possible that ancient rulers were, in fact, connected with divine or, some would say, extraterrestrial forces? And, if so, what was their purpose? Ancient emperors, kings, and pharaohs were often attributed with otherworldly strength, ability, and wisdom; many were even considered gods by the people they ruled. Who were these exceptional leaders, and how did some accomplish so much in their time? Ancient Astronaut theorists believe that these great rulers throughout history were "chosen" and guided by extraterrestrials. Is it possible that the world's legendary leaders might have shared a common genetic trait? A so-called, "leadership gene"? And might this gene have been--not a product of genetic evolution--but inherited by mankind from some otherworldly source?

Mysterious surgeries performed by early humans... Strange beings with miraculous powers... And a cover up--destroying centuries of scientific knowledge. Are recent breakthroughs in medicine the result of years of research?

He is the evil one, the Prince of Darkness, the ruler of Hell. Satan conjures up horrifying images of a horned beast whose sole purpose is to destroy humanity. Yet there is evidence that the fallen angel we know as Satan may be misunderstood.

Wondrous wizards... Mysterious sorcerers... And heavenly beings... possessed of unimaginable power. Throughout the ancient world, magic was used for everything from healing to communicating with the gods. But did magic really exist in the ancient times? Not as a form of theater - but as a means of replicating the power of the gods? Do ancient accounts of magic suggest evidence of advanced, otherworldly knowledge? A knowledge given to early humans as a means of helping them unlock their own - some might say "divine" - potential?

In ancient Mesopotamia, the Sumerians make advances in agriculture, science, medicine, and astronomy, crediting these achievements to winged gods known as the Anunnaki.

Luminous relics in the shape of human skulls. Otherworldly artifacts believed to harness the secrets of the universe. Are the Crystal Skulls part of an elaborate hoax? Or do they possess a great, perhaps even otherworldly power?

The ancient Egyptians built the three pyramids of Giza in a formation; diverse cultures worship the all-knowing triads; an ancient tablet mentioned the power of the number three; the language of human DNA is written in a pattern of threes.
