The world-famous bestseller Chariots of the Gods introduced the theory that ancient Earth had established contact with aliens. Now, Erich von D niken's The Eyes of the Sphinx reveals startling evidence that could prove it. Erich von D niken's theory of alien contact with the ancient world is so incredible, yet so logical and convincing, that it has become part of a wide-ranging debate that continues to this day.

And it is these ruins that now provide researchers with a never-ending source of clues, compelling discoveries, revelations, and evidence that Earth was indeed colonized by an alien race.
