Photon Propulsion

Photon Propulsion is technology that would allow a large, ocean-liner-sized rocketship to achieve speeds at 99% of the speed of light. Through this type of propulsion, it would be possible to visit worlds many light-years away; this is precisely the type of technology needed for alien astronauts to visit Earth, and eventually for mankind to visit other planets.

Nazca Lines

The famous Nazca lines, made by Incas in the shape of geometrical patterns and animals is, for Von Däniken, a piece of evidence for the existence of alien astronauts. Von Däniken believes it would be impossible for the Incas to manufacture these huge shapes without advanced aerial and surveying technology. These lines may, in fact, be runways or signs made for returning astronaut "gods."
