Answer : E.T (EXTRA TERRESTRIAL) LIFE
Extraterrestrial life, sometimes colloquially referred to as alien life, is hypothetical life that may occur outside Earth and which did not originate on Earth.
extraterrestrial life, life that may exist or may have existed in the universe outside of Earth. The search for extraterrestrial life encompasses many fundamental scientific questions. What are the basic requirements for life? Could life have arisen elsewhere in the solar system? Are there other planets like Earth? How likely is the evolution of intelligent life?
UNIVERSAL CRITERIA
No one knows which aspects of living systems are necessary, in the sense that living systems everywhere must have them, and which are contingent, in the sense that they are the result of evolutionary accidents such that elsewhere a different sequence of events might have led to different properties of life. In this respect the discovery of even a single example of extraterrestrial life, no matter how elementary in form or substance, would represent a fundamental revolution in science. Do a vast array of biological themes and counterpoints exist in the universe, or are there places with living fugues, compared with which Earth’s one tune is a bit thin and reedy? Or is Earth’s the only tune around?
THE SEARCH FOR EXTRATERRESTRIAL LIFE
Astrobiology, a term coined for the study of all life anywhere in the universe (including Earth), has replaced exobiology, the study of extraterrestrial life exclusively and therefore criticizable as “a science that lacks a subject matter.” Unlike exobiology, astrobiology respects the scientific possibility that life beyond Earth may never be found. Indeed, no evidence for life beyond Earth has been adduced. However, the design of astrobiological experiments forces critical examination of the generality of assumptions derived from Earth life.
