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:
““From those constellations turn
Your eyes, and sleep; for every man
Is living; and for peace upon
His life should rest;
This must everybody learn
For mutual happiness; that trust
Alone is best.””
—Philip Larkin (1922–1986)
