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:
“Franceska: I was happy in the life I built up for myself. I put a fine high wall of music around me and nothing could touch me. I was safe and secure. And then you had to come along and knock it all down and I hate you for that.
Maxwell: On the contrary, you love me.”
—Muriel Box (b. 1905)
