Ancient Aliens Exposed! A Skeptical Look At The TV Phenomenon Or otherwise titled A Critical Look at Ancient Aliens and other Galactic Bunk Ancient Aliens is an American television program that premiered on the so-called History Channel on April 20, 2010. The show supports the ancient astronaut theory, which believes that many historical texts, archeological sites and legends contain evidence of past alien contact. Ancient Aliens Exposed takes a skeptical look at some of the main claims made by this show and finds them wanting. If you or anyone you know has ever been taken in by the sheer hokum of this series, consider this little book the antidote.
