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:
“Such was life in the Golden Gate:
Gold dusted all we drank and ate,
And I was one of the children told,
“We all must eat our peck of gold.””
—Robert Frost (1874–1963)
