extraterrestrial life
life that does not originate from Earth
AI overview
Extraterrestrial life refers to any living organisms that exist or originated somewhere in the universe beyond Earth. Scientists study the possibility of extraterrestrial life because understanding whether life exists elsewhere would fundamentally change our knowledge of biology, our place in the universe, and the conditions necessary for life to develop.
