Extraterrestrial life (or life in outer space) is a hypothesis that there may be life in the universe whose natural environment is not Earth. This concept refers to any type or form of life, from the simplest biological systems (eg viruses and prokaryotes) to the most complex forms of life with their own intelligence and social organization. However, the existence of life outside the Earth would have been 95% proven in 2013 by a team of British researchers from the Department of Molecular Biology and Biotechnology at the University of Sheffield. [1] [2] The age of the Universe, huge, as well as the enormous number of stellar systems suggest that if the Earth were a model of celestial bodies with generally valid life, then extraterrestrial life should be encountered in the Universe quite often [3]. There is also an obvious contradiction between the probability of the existence of extraterrestrial civilizations in the Universe, probability estimated to be small but real, and the lack of contacts with such civilizations or other evidence of their existence, a contradiction called Fermi's paradox. 1
