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:
“Unable to create a meaningful life for itself, the personality takes its own revenge: from the lower depths comes a regressive form of spontaneity: raw animality forms a counterpoise to the meaningless stimuli and the vicarious life to which the ordinary man is conditioned. Getting spiritual nourishment from this chaos of events, sensations, and devious interpretations is the equivalent of trying to pick through a garbage pile for food.”
—Lewis Mumford (1895–1990)
