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 sheets and towels of a life we were going to share,
The milk-stiff bibs, the shroud, each rag to be ever
Trampled or soiled, bled on or groped for blindly,
Came swooning out of an enormous willow hamper
Onto moon-marbly boards.”
—James Merrill (b. 1926)
