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:
“Holinesse on the head,
Light and perfections on the breast,
Harmonious bells below, raising the dead
To leade them unto life and rest.
Thus are true Aarons drest.”
—George Herbert (1593–1633)
