Our Ancestors' Otherworldly Past

This Ancient Aliens compilation explores the possibility that our ancestors encountered visitors from beyond Earth. It considers mysterious ruins, gods and strange creatures, asking whether they could be connected to extraterrestrial visitors.

The idea that extraterrestrials came to Earth in the distant past is a controversial theory, not an established fact. The program presents it as part of Ancient Aliens’ broader examination of possible links between extraterrestrials and human history.
