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:
“His meter was bitter, and ironic and spectacular and inviting: so was life. There wasn’t much other life during those times than to what his pen paid the tribute of poetic tragic glamour and offered the reconciliation of the familiarities of tragedy.”
—Zelda Fitzgerald (1900–1948)
