- This is from a scientific point of view. For aliens in popular culture see extraterrestrial life (popular culture). For other uses, see Extraterrestrial (disambiguation).
Extraterrestrial life is life that may exist and originate outside the planet Earth, the only place in the Universe known to support life. Its existence is currently hypothetical; there is as yet no evidence of extraterrestrial life that has been widely accepted by scientists.
Most scientists hold that if extraterrestrial life exists, its evolution would have occurred independently in different places in the universe. An alternative hypothesis, held by a minority, is panspermia, which suggests that life in the universe could have stemmed from a smaller number of points of origin, and then spread across the universe, from habitable planet to habitable planet. These two hypotheses are not mutually exclusive.
