The author suggests new vision of mechanism of initiation of life on the planets after Tunguska similar impacts. This mechanism takes into consideration not only incoming cosmic organic substance but also information, which is connected to this substance. Mathematical metrics of atom of hydrogen is deduced which may be used for pattern recognition algorithm. In accordance to author's opinion, similar algorithm can promote evolution (transformation) of inert organic substance into living substance. The fact of a survival of vegetation after the Tunguska event is analyzed especially. Also the author checked up his probably Tunguska meteorites by strong magnet. The presence of magnetic substance was detected with concentration of 10-2 % during this test.
