New concept of the life prehistory is proposed. It is based on experimentally obtained results and provides evidences of possibility of the simplest life forms creation in the plasma torch formed at the super high velocity (SHV) meteorite impact.

It has been shown experimentally that the impact plasma torch represents highly non-uniform media that has high catalytic properties and ensures the synthesis of complicated polymer organic compounds and their self-organisarion.

Experimentally found unidirected nonequilibrium electromagnetic fields of the torch contribute to the formation of local chiral physical fields that could define the asymmetry 'sign' of bio-organic world as well as contribute to the appearance of homochiral molecular structures in the processes of spontaneous breaking the mirror asymmetry of sinthesized enatiomers.

Hypothetic model of extraterrestrial life origin is proposed using specific features of 'penetrating' meteoritic impact.

The assumption is sunstantiated according to which the OC synthesis in interstellar gas-dust clouds occurs in similar processes at SHV - collisions bettween dust particles.

The main ideas of this concept were confirmed by results of series of laboratory experiments modeling the impact processes.
