Some proofs that "Ancient Aliens" insist.

Stone Henge - Even today the origin and meaning of Stone Henge is a mystery.

Statue of Akhenaten - Akhenaten ascended to the throne as the 10th Pharaoh of the 18th dynasty in 1352 B.C. He is depicted in paintings and carvings with an elongated skull, which some ancient alien theorists see as a sign of extraterrestrial heritage.  The picture below is his possible skull.

Because of their colossal size, the figures can only be appreciated from way up in the air —and there is no evidence that the Nazca people, who inhabited the area between 300 B.C. and 800 A.D., invented flying machines. According to ancient alien theorists, the figures were used to guide spaceships as they came in for a landing, and the lines served as runways.

Approximately 500 years old, these monolithic statues stand 13 feet high and weigh 14 tons, but some are twice as tall and much heavier. How could human beings without sophisticated tools or knowledge of engineering craft and transport such incredible structures? Some ancient alien theorists believe it is the work of visiting extraterrestrials who left their mark on the island.
