Books like chariots of the gods?

Chariots of the Gods? Unsolved Mysteries of the Past (German: Erinnerungen an die Zukunft: Ungelöste Rätsel der Vergangenheit; in English, Memories of the Future: Unsolved Mysteries of the Past) is a book written in 1968 by Erich von Däniken and translated from the original German by Michael Heron. It involves the hypothesis that the technologies and religions of many ancient civilizations were given to them by ancient astronauts who were welcomed as gods.

The first draft of the publication had been rejected by a variety of publishers. The book was extensively rewritten by its editor, Wilhelm Roggersdorf (a pen name of the German screenwriter Wilhelm "Utz" Utermann).

Chariots of the Gods posits a variety of hypotheses dealing with the possibility of extraterrestrial beings influencing ancient technology. Von Däniken suggests that some ancient structures and artifacts appear to represent higher technological knowledge than is presumed to have existed at the times they were manufactured. Von Däniken maintains that these artifacts were produced either by extraterrestrial visitors or by humans who learned the necessary knowledge from them.
