Ancient Aliens

- Season 10

(2015)

Enormous manmade caves... Unexplainable structures... And underwater discoveries that challenge everything we know about the past...Is it possible that an advanced civilization inhabited Earth thousands of years ago?

When German aerospace engineer Wernher von Braun joined the U.S. military and space programs after World War II, he quickly became one of the foremost scientists credited with developing the ballistic missile, the first American satellite and the enormous Saturn V rocket that enabled man to reach the moon. Von Braun's bold predictions that we would explore Mars and build a space station have become reality. But how is it that von Braun-whose contemporaries included such scientific geniuses as Nikola Tesla, Robert Oppenheimer, and Albert Einstein-was so far ahead of ...

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.

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.

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.

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?"

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.

Over 10,000 crop circles have been reported worldwide, appearing in 50 different countries, and nearly every continent on Earth. These strange designs pressed into crop fields range from simple circles to elaborate pictograms thousand of feet long. The phenomenon has been associated with scientific anomalies, strange lights, and even UFO activity.

Could clues about our extraterrestrial origins be hidden in these discarded pieces of our past? Shocking evidence has recently been revealed that challenges the accepted dating of the Great Pyramid.

Specific regions of the world that are off-limits to exploration due to warfare, instability and inaccessibility.
