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:
“The deadly monotony of Christian country life where there are no beggars to feed, no drunkards to credit, which are among the moral duties of Christians in cities, leads as naturally to the outvent of what Methodists call “revivals” as did the backslidings of the people in those days.”
—Corra May Harris (1869–1935)
