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 have spent so long erecting partitions around the part of me that writes—learning how to close the door on it when ordinary life intervenes, how to close the door on ordinary life when it’s time to start writing again—that I’m not sure I could fit the two parts of me back together now.”
—Anne Tyler (b. 1941)
