Erich von Daniken, who devoted his life to studying the Earth's past, defends a theory that academic science does not recognize. In his opinion, we owe the birth of life on our planet and the development of earthly civilization to aliens. This book is devoted to the justification of this theory. The author bases his arguments on archaeological facts and books of books of different religions, in which, in his opinion, visits of representatives of extraterrestrial civilizations are recorded.
