Internal water oceans on planets and planetary satellites are considered as likely ‘shelters’ of a microbial life that could spontaneously origin in the Solar System. Widespread in the Universe three-atomic molecules of HCN and H2O and derivative from them formamide (NH2COH) could be initial blocks for the primitive terrestrial and extraterrestrial life forms (e. g., Pino et al., 2013). As shown recently in laboratory experiments (JINR, Dubna, Russia), Saladino et al., 2015), irradiation of formamide by protons in the presence of mineral or meteoritic catalyzers leads to synchronous synthesis of a wide range of prebiotic compounds (amino acids, heterocycles, alcohols, amides, sugars, etc.) potentially relevant to develop genetics (based on RNA and DNA) and metabolism underlying the terrestrial life (Pino et al., 2013). As suspected, proton irradiation of formamide creates active radicals stimulating effectively a further synthesis. Noteworthy, such types of synthesis are abiotic and run in the same chemical environments. Finds of possible fossilized microbial structures in carbonaceous chondrites with an extremely high age ~4.5-4.6 Gyr points likely to origin of microbial life before the formation of Earth. Here we out-line processes that could create appropriate conditions for biological synthesis at the very beginning of our plan-etary system formation.
