Extraterrestrial life - Dealing with extraterrestrial life

Extraterrestrial life is life that may exist and originate outside the planet Earth. Its existence is currently hypothetical: there is as yet no evidence of extraterrestrial life that has been widely accepted by scientists. Most scientists hold that if extraterrestial life exists, its evolution would have occurred independently in different places in the universe. An alternative hypothesis, held by a minority, is panspermia, which suggests that life in the universe could have stemmed from a single initial distribution of spores ...

Extraterrestrial life - Ancient and Early Modern ideas. See also: Cosmic pluralism Belief in extraterrestrial life may have been present in ancient Egypt, Babylon, and Sumer, although in these societies, cosmology was fundamentally supernatural and the notion of aliens is difficult to distinguish from that of gods, demons, and such. The first important Western thinkers to argue systematically for a universe full of other planets and, therefore, possible extraterrestrial life were the an ...

Many bodies in the Solar System have been suggested as being likely to contain life. The most commonly suggested ones are listed below; of these, four of the five are moons thought to have large bodies of underground liquid, and life may have evolved there in a similar fashion to deep sea vents. Mars - The best known of the other planets and moons in the Solar system. There was liquid water on Mars in the past and there may be liquid water beneath the surface. Recently, methane was found in the atmosphere of Mars. For more infor ...

Extraterrestrial life - Biochemistry. Main article: Alternative biochemistry All life on Earth is based on the building block element carbon with water as the solvent in which bio-chemical reactions take place. Given their relative abundance and usefulness in sustaining life it has long been assumed that life forms elsewhere in the universe will also utilize these basic components. However, other elements and solvents might be capable of providing a basis for life. Silicon is usually considered the ...

The scientific search for extraterrestrial life is being carried out in two different ways, directly and indirectly. Extraterrestrial life - Direct search. Scientists are directly searching for evidence of unicellular life within the solar system, carrying out studies on the surface of Mars and examining meteors that have fallen to Earth. A mission is also proposed to Europa, one of J ...
