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 poet’s body even is not fed like other men’s, but he sometimes tastes the genuine nectar and ambrosia of the gods, and lives a divine life. By the healthful and invigorating thrills of inspiration his life is preserved to a serene old age.”
—Henry David Thoreau (1817–1862)
