The "Ancient astronauts" theory refers to the idea that extraterrestrial beings visited Earth in the past.
Ancient Astronaut Theorists believe that those extraterrestrial beings ("the ancient aliens") helped ancient cultures developing technology and building some of the most unexplainable artefacts and buildings. "Out-of-place artifact" (OOPart) is the name they give for artifacts that apparently could not have been created by a known culture.
“We are made of stardust, our whole body consists of material that has been here before the beginning of time.”
-Giorgio A. Tsoukalos
