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:
“The detective novel is the art-for-art’s-sake of our yawning Philistinism, the classic example of a specialized form of art removed from contact with the life it pretends to build on.”
—V.S. (Victor Sawdon)
