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 cinema is not an art which films life: the cinema is something between art and life. Unlike painting and literature, the cinema both gives to life and takes from it, and I try to render this concept in my films. Literature and painting both exist as art from the very start; the cinema doesn’t.”
—Jean-Luc Godard (b. 1930)
