The word "extraterrestrial" is derived from the Latin extra ("outside", "outwards") and terrestris ("earthly", of or relating to the Earth). The existence of such life is theoretical and all assertions about it remain disputed. Hypotheses regarding the origin(s) of extraterrestrial life, if it exists, are as follows: one proposes that it may have emerged, independently, from different places in the universe; an alternative hypothesis is panspermia or exogenesis, which holds that life emerges from one location, then spreads among habitable planets. These two hypotheses are not mutually exclusive. The study and theorization of extraterrestrial life is known as astrobiology, exobiology or xenobiology. Speculated forms of extraterrestrial life range from life with the simplicity of bacteria to sentient or sapient beings which are more advanced than humans.
