"Chariots of the Gods?" is a book written by Swiss author Erich von Däniken in 1968. It explores the idea that ancient civilizations were visited by extraterrestrial beings, who influenced human culture and technology. The book presents various archaeological findings and historical texts as evidence for these claims. Von Däniken suggests that many ancient structures, such as the Pyramids of Giza and Stonehenge, could not have been built without advanced knowledge or assistance from these visitors. The book sparked significant interest and debate about the possibility of ancient aliens and their impact on human history.
