In popular cultures, "Extraterrestrials" are life forms — especially intelligent life forms— that are of extraterrestrial origin (often also called "aliens").
Famous quotes containing the word life:
“You know all my life I’ve hated funerals. The fuss and bother never brings anybody back. It just spoils remembering them as they really are. And when I see people actually facing it that way, I have to act like a sap.”
—Jules Furthman (1888–1960)
