n. (plural of ancient astronaut English)
Ancient astronauts (or ancient aliens) is a pseudoscientific concept based on the belief that intelligent extraterrestrial beings visited Earth and made contact with humans in antiquity and prehistoric times. Proponents suggest that this contact influenced the development of modern cultures, technologies, and religions. A common claim is that deities from most, if not all, religions are actually extraterrestrial in origin, and that advanced technologies brought to Earth by ancient astronauts were interpreted as evidence of divine status by early humans.
Proponents in the latter half of the 20th century include Erich von Däniken, Giorgio Tsoukalos, Zecharia Sitchin, Robert Temple, David Icke, Peter Kolosimo, and Robert Charroux.
The idea that ancient astronauts actually existed is not taken seriously by academics, and has received no credible attention in peer reviewed studies. Ancient astronauts have been widely used as a plot device in science fiction.
