#3 - The Crystal Skulls
S6:E210/7/2013
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 Crystal Skulls are some of the most controversial of ancient artifacts. While there have been literally hundreds of crystal skulls found throughout the world, according to legend, there are only thirteen which are believed to hold an awesome, mystical power whose secrets will be revealed when the skulls come together to form a global grid. Could this so-called "reunion of the skulls" awaken sacred knowledge of the gods? Knowledge that has been hidden from mankind for thousands of years? And if so, will the Crystal Skulls reveal the truth about our extraterrestrial past, or offer us a glimpse into our future?

#8 - The Satan Conspiracy
S6:E510/28/2013
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. New interpretations of ancient texts indicate that Satan may have been an extraterrestrial who was more of an ally to humanity than an enemy by passing along knowledge that planted the seed for civilization. Could Satan's reputation as the personification of evil be his punishment for leading early man out of darkness and ignorance? If so, might his evil acts really be expressions of revenge against the human creatures that abandoned him? Or are the devilish deeds associated with Satan part of a grand plan? A series of moral challenges intended to prepare us for our next, and perhaps final... close encounter?

Amazonian shamans believe otherworldly beings taught them how to create a powerful brew that allows them to travel beyond Earth to gain knowledge. And on the desert plains of the Kalahari, the San Bushmen practice elaborate trance dances that unlock supernatural capabilities in their healers. Can shamans really communicate with otherworldly beings? Is it possible that through these spiritual mediators, extraterrestrials were able to influence mankind in the distant past?

#10 - The Reptilians
S8:E47/25/2014
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 Mexico and Central America people worshiped the feather serpent god called Kukulkan 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?

#11 - Aliens and the Civil War
S9:E94/10/2015
The Civil War nearly destroyed the great experiment known as the United States of America, but is it possible that the preservation of the republic was influenced by extraterrestrial beings? Abraham Lincoln described strange visions and premonitions that occur before pivotal moments in his presidency. Union officer Ambrose Bierce wrote about mysterious disappearances and inter-dimensional travel. And a ghostly image of George Washington was witnessed by hundreds of soldiers at Gettysburg–prompting an official government investigation. Is it possible that extraterrestrials were present during the Civil War? If so, were they simply passive observers, waiting to see if our fragile democracy could survive this test? Or did they take an active roll in order to preserve the Union?

Is it possible there are children being born on Earth today who can access their alien DNA--a connection that endows them with special gifts and the power to transform society?

#16 - Magic of the Gods
S6:E410/21/2013
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?

S6:E611/1/2013
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? Or does the knowledge of healing really come from an otherworldly source? Evidence of advanced medical procedures practiced in the ancient world has been found everywhere from carvings on the walls of temples to actual skeletal remains. But just who were the practitioners of this extraordinary science? And where did their knowledge of the human body come from? Accounts from various cultures describe similar divine, birdlike figures that brought advanced medical knowledge to mankind thousands of years ago. Who--or what--were these ancient surgeons? Is it possible that these Gods may have been extraterrestrial beings that came to Earth to teach humans how to heal themselves?

#18 - Emperors, Kings and Pharaohs
S6:E711/8/2013
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?

#24 - The Tesla Experiment
S8:E58/1/2014
He is one of the most prolific inventors of the 20th century--and the man that actually electrified the world. Nikola Tesla shepherded mankind to a new industrial era and laid the groundwork for today's technological age--but could that have been by some otherworldly design? A man shrouded in mystery and intrigue, Tesla would speak about obtaining insights in a flash of genius, how he could visualize his inventions in full-detail and manipulate them in his mind, and his compulsion to invent the future. But he also claimed to have direct communication from intelligent beings on other planets. Is it possible that this alleged mad scientist, so far ahead of his time, was actually a human "receiver"? A being tapped to advance mankind--and pave the way for a future reunion with our alien ancestors?

#25 - Creatures of the Deep
S10:E79/4/2015
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?
