"Idyllic life on Pacifista changes rapidly for Pachuco and Mirasol when they learn that a large asteroid is on a collision course with their planet. The two must now travel via intergalactic space glider back to Earth, back to Albuquerque, New Mexico, in order to find the solution to this crisis. Their quest takes them into the realm of science at Los Alamos National Laboratory, and into the realm of Navajo spirituality and ritual."--

The breakthrough book that was immediately recognized as a work of monumental importance when it first introduced the theory that ancient earth had established contact with aliens. This world-famous bestseller endures as proof that Earth has been visited repeatedly by advanced aliens from other worlds. Erich von Däniken examines ancient ruins, lost cities, space-ports, and a myriad of hard scientific facts that point to extraterrestrial intervention in human history. Most incredible of all, however, is von Däniken's theory that we ourselves are descendants of these galactic pioneers--and the archeological finds that prove it: 1.Sophisticated batteries found in Bronze Age cities 2.An alien astronaut preserved in a pyramid 3.Thousand-year-old spaceflight navigation charts 4.Computer astronomy from Incan and Egyptian ruins 5. A map of the land beneath the ice cap of Antarctica 6. A giant spaceport discovered in the Andes
