Аннотация:Widespread in the interstellar medium three-atomic molecules of HCN and H2O and derivative formamid (NH2COH) are the basis for the origin of life. It is shown that irradiation of formamid by protons in the presence of terrestrial mineral and meteoritic catalysts in conditions compatible with terrestrial leads to simultaneous synthesis of a wide range of compounds (amino acids, heterocycles, alcohols, amides, sugars, etc.) having potential to develop as genetics (based on RNA and DNA), and metabolism underlying terrestrial life forms [1, 2]. However, the intended path of extraterrestrial origin of life in the open interstellar medium could not reach its logical end. The subsequent stages of the assumed biological synthesis needed protection from the harsh cosmic factors and presence of liquid water, catalysts, etc. (e.g., [3]). Such conditions could be realized only on planetary bodies and/or in their interiors. On the basis of observations and calculations, the author suggested that the objects were in the early Solar system. Such could be stone-ice bodies.
