The Case of Ancient Astronauts (1979: Carl Sagan, Erich Von Daniken)

Examines the claims made by Erich Von Daniken in his book Chariots Of The Gods that astronauts from other worlds have already visited Earth, and have left evidence, such as the pyramids and the statues on Easter Island. Takes the position that Von Daniken's book contains inaccuracies, unrelated facts and unsubstantiated evidence.
