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:
“I could lie down like a tired child,
And weep away the life of care
Which I have borne and yet must bear,
Till death like sleep might steal on me,”
—Percy Bysshe Shelley (1792–1822)
