The History Channel continues its popular series on on extraterrestrials, alien theorists and ancient civilizations with season two of Ancient Aliens.

The following video playlist constitutes program ten, entitled Alien Messengers and runs for 44 minutes. It examines whether extraterrestrials use members of the human population to communicate their message. What if ancient aliens shape our history, evolution, religions and mythologies? Have they been helped by individuals among us to communicate important messages?

"What if life on Earth began in outer space? Millions of people accept the theory that intelligent life forms visited Earth thousands of years ago and were worshiped as gods by primitive man. Are monuments like Stonehenge and Easter Island the last remains of an ancient alien visitation? From unexplainable super structures, to knowledge of the solar system, mathematics, and even the ability to make electricity, this special explores evidence of super-human influences on ancient man and embarks on an around-the-world search for answers." - History Channel.
