An extraterrestrial or alien is any extraterrestrial lifeform: a lifeform that did not originate on Earth. The word extraterrestrial means "outside Earth". The first published use of extraterrestrial as a noun occurred in 1956, during the Golden Age of Science Fiction.[1][dubious – discuss]
Extraterrestrials are a common theme in modern science-fiction, and also appeared in much earlier works such as the second-century parody True History[2] by Lucian of Samosata.[3]
