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:
“There are three times in a man’s life when he has the right to yell at the moon—when he marries; when his children come; and when he finishes a job he had to be crazy to start.”
—Borden Chase [Frank Fowler] (1900–1971)
