Evidence to Clinch the Theory of Extraterrestrial Life

New data may serve to bring about the long overdue paradigm shift from theories of Earth-centred life to life being a truly cosmic phenomenon. The theory that bacteria and viruses similar to those on Earth exist in comets, other planets and generally throughout the galaxy was developed as a serious scientific discipline from the early 1980’s. Throughout the past three decades this idea has often been the subject of criticism, denial or even ridicule. Even though many discoveries in astronomy, geology and biology continued to provide supportive evidence for the theory of cosmic life, the rival theory of Earth-centered biology has remained deeply rooted in scientific culture. However, several recent developments are beginning to strain the credibility of the standard point of view. The great abundance of highly complex organic molecules in interstellar clouds, the plentiful existence of habitable planets in the galaxy numbering over 100 billion and separated one from another just by a few light years, the extreme space-survival properties of bacteria and viruses -make it exceedingly difficult to avoid the conclusion that the entire galaxy is a single connected biosphere. The patterns of evolution of life found on the Earth are therefore likely to be repeated on countless planets, with each individual planetary environment selecting its genetic inheritance from a vast cosmic reservoir of genes. These ideas have been elaborated upon in several papers.
