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:
“... it is a rather curious thing to have to divide one’s life into personal and official compartments and temporarily put the personal side into its hidden compartment to be taken out again when one’s official duties are at an end.”
—Eleanor Roosevelt (1884–1962)
