ALIENS are extraterrestrial life that is life that exists and originates outside the planet Earth, the only place in the universe currently known by humans to support life.

The aliens existence is still hypothetical as there is currently little, if any, evidence to indicate that other planets can support life, and there is no evidence of extraterrestrial life that has been widely accepted by the scientific community.

Some, however, point to moons of Jupiter or other celestial bodies that might conceivably have some forms of life (bacterial or otherwise). Most scientists believe that if extraterrestrial life exists, its evolution occurred independently, in different places. An alternative hypothesis, held by a minority, is panspermia. This suggests that life could have been created elsewhere and spread across the universe, between habitable planets. These two hypotheses are not mutually exclusive. The putative study and theorisation of extraterrestrial life is known as astrobiology or xenobiology. Speculative forms of extraterrestrial life range from sapient beings to life at the scale of bacteria. Since no examples of confirmed extraterrestrial life are available for examination, these studies presently remain within the realm of speculation.
