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:
“Margaret: Some people have life made for them.
Frank: That’s right, Mrs. Hammond, and some people make it for themselves. It’s about time you took that ton of rock off your shoulders.”
—David Storey (b. 1933)
