Scrambled to find in meteorites, some indications of organic life, but these efforts were unsuccessful, only carbonaceous meteorites represent in its composition, as it were some traces of living beings. But no traces of organisms still says nothing against the possibility of the population. Before reaching the Earth, meteorites moving in a cold world space, away from the sun and other heat-emitting stars, and has a temperature of 100 degrees below the freezing point: hence the incredibly admit the existence of them living beings: a meteorite Kvenguka immediately after the fall was so cold that to the touch in his fingers lost any sensitivity. And if the meteorites, and there are organisms, then in any case, the conditions of their lives so different from ours that we can not make any representations about them. It has been suggested that the first organisms were placed on the earth by meteorites, in view of the foregoing, it seems unlikely. Granites occurring under all layered rocks, almost entirely absent in meteorites, the latter only contain anorthite and olivine rocks, which are submitted to the Earth's surface by volcanic eruptions and are inside the earth in large quantities. Until now, the comparison of meteorites with terrestrial rocks not difficult, but as soon as we touch meteoric iron, but now serves a number of unanswered questions. At first glance it seems that it has no kinship with rocks host a significant part in the structure of the earth: native iron is very rare, and a few years ago it was not considered part of the Earth. But many considerations do not allow for such a quick conclusion. Speaking about the weight of the Earth, we learn that he is much more than the weight that we could calculate, assuming that the entire mass of our planet consists of the same rocks that we find on its surface.
