Erich von Daniken, whose books have enthralled millions of readers around the world, now presents astonishing new confirmation for his revolutionary theories. From a mysterious system of caves and tunnels (filled with gold!) in Ecuador to the ancient ruins of Nan Madol in Micronesia (composed of basalt blocks impossible to transport without advanced technology) the author explores the inexplicable artifacts of bygone ages. Elucidating undeciphered writings and drawings in solid gold which take us back in time to the Great Flood, he ultimately suggest an intergalactic "battle of the gods" whose losers retreated to, and settled, our earth. Includes an introduction and update by Ancient Aliens star David Hatcher Childress. First released in 1974, this classic book about an underground world in South America is back in print! 8-page color section.
