What is Extraterrestrial Life? popular

10 out of 10 stars (55 votes)

Extraterrestrial life (from the Latin words: extra ("beyond", or "not of") and‎ terrestris ("of or belonging to Earth")) is defined as life that does not originate from Earth. Also referred to as alien life, or simply aliens, these hypothetical forms of life range from simple bacteria-like organisms to beings far more advanced than humans. The development and testing of theories about extraterrestrial life is known as exobiology or astrobiology; the term astrobiology, however, also covers the study of life on Earth, viewed in its astronomical context. Although many prominent scientists consider extraterrestrial life to be plausible, the scientific community does not currently recognize any verifiable evidence of such life.
