Answer:

Extraterrestrial life is hypothetical life which may occur outside of Earth and which did not originate on Earth.

Answer 2

Extraterrestrial life[n 1] is hypothetical life which may occur outside of Earth and which did not originate on Earth. Such life might range from simple prokaryotes (or comparable life forms) to intelligent beings and even sapient beings, possibly bringing forth civilizations which might as well be far more advanced than humanity.[1][2] The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as astrobiology.
