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:
“Since it is impossible to know what’s really happening, we Peruvians lie, invent, dream and take refuge in illusion. Because of these strange circumstances, Peruvian life, a life in which so few actually do read, has become literary.”
—Mario Vargas Llosa (b. 1936)
