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 think of horror films as art, as films of confrontation. Films that make you confront aspects of your own life that are difficult to face. Just because you’re making a horror film doesn’t mean you can’t make an artful film.”
—David Cronenberg (b. 1943)
