The book, Chariot of the Gods by von Däniken, was considered radical when first published, but its success is due to the simplicity of the explanation it offered. Offering a web that encompassed cave man drawings, landing strips high in the Andes, and the current experiences of man out in space, was a hit. Few could find fault with the logic, which was in fact based on truth, and this has held through criticism. By giving a rational argument to the concept of visitors, Van Daniken is to be applauded.
