Ancient Astronaut Hypothesis
The theory that extraterrestrial beings visited Earth in antiquity, influencing human civilization, technology, and religion.
OVERVIEW
The ancient astronaut hypothesis proposes that intelligent extraterrestrial beings visited Earth in the distant past and influenced or directly aided the development of human civilization. Proponents point to ancient texts describing sky gods, structures that appear beyond contemporary capabilities, and artifacts that seem to depict spacecraft or beings with advanced technology. The theory was popularized by Erich von Däniken's 1968 book 'Chariots of the Gods?' and later by the History Channel series 'Ancient Aliens.' Mainstream archaeologists reject the hypothesis, providing alternative explanations for the same evidence.
