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:
“Life on board a pleasure steamer violates every moral and physical condition of healthy life except fresh air.... It is a guzzling, lounging, gambling, dog’s life. The only alternative to excitement is irritability.”
—George Bernard Shaw (1856–1950)
