Annotation

The problem of the origin of life is discussed from the astrophysical point of view. Most biologists and geologists have believed up to the present time that Life originated on the Earth in some initial natural chemical prereactors, where a mixture of the water, ammonia, methane containing species and some other substances, under the influence of an energy source like, e.g. lightning, had turned into quite complex compounds such as amino acids and complex hydrocarbons. In fact, under conditions of the primordial Earth, it was not possible to obtain such prebiological molecules by a-bio-chemical methods, as discussed in this paper. Instead, an astrophysical view of the problem of the origin of life on the Earth is proposed and it is recalled that the biological evolution on the Earth was preceded by the chemical evolution of complex chemical compounds, mostly under extraterrestrial conditions, where it is only possible to form optically active amino acids, sugars and hydrocarbons necessary for constructing the first pre-biomolecules.
