Erich Von Daniken Ancient Alien Structures and Artifacts [Full Video]

Erich von Daniken put forth his hypothesis that, the technologies and religions of many ancient civilizations were given to them by space travelers who were welcomed as gods. He is regarded by many as the father of ancient alien theory, also known as the ancient astronaut theory. Since that time, he has written many other books and appeared in media presenting physical proof of his theories.

The types of evidence von Daniken cites can be categorized as follows:

The existence of structures and artifacts have been found which represent higher technological knowledge than is presumed to have existed at the times they were manufactured. 

Daniken maintains that these artifacts were produced either by extraterrestrial visitors or by humans who learned the necessary knowledge from them.
