Extra-terrestrial life & the UFO phenomenon
Extraterrestrial
Originating outside Earth — often used for claimed non-human intelligence tied to UFO/UAP discussions.
“Extraterrestrial” is a conclusion about origin. Many researchers prefer to describe the observation first and keep ET as one hypothesis among others.
ET as a two-letter alias is matched carefully as a whole word so ordinary words are not linked.
