Our Ancestors Came from Outer Space is a non-fiction book by French-American aerospace engineer and author Maurice Chatelain. First published in English in 1978, the book explores the ancient astronaut theory, proposing that extraterrestrial beings visited Earth in the distant past and influenced human civilization.

Summary

Core Theory: Chatelain argues that advanced extraterrestrials from another solar system came to Earth and crossbred with Neanderthals, leading to the creation of Cro-Magnon people, our direct ancestors.

Evidence: He uses his background in aerospace and communications, along with interpretations of ancient texts, myths, and archaeological findings (such as the Egyptian pyramids and the Mayan calendar), to present what he considers "undeniable proof" of alien influence.

Controversy: The claims in the book are considered controversial and speculative within scientific circles, with critics arguing they lack concrete evidence and rely on speculative interpretations of history and artifacts.
