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 extrovert and introvert, the realist and idealist, the scientist and philosopher, the man who found himself by refinding his life history and the individual who discovered his being in fantasy, these are the differences between Freud and Jung.”
—Robert S. Steele. Freud and Jung: Conflicts of Interpretation, ch. 10, Routledge & Kegan Paul (1982)
