Clouds from which the sun and the planets were formed, 99 percent consisted of a mixture of hydrogen and helium, and the other chemical elements had quite a bit - 1-2 percent. Most of the clouds went to form the Sun and the smaller became the material for planet formation. Many scientists believe that hydrogen was carried by the solar wind before the end of planet formation. However, analysis of the geological structure of the Earth showed that in the first 500-600 million years of existence, it was surrounded by a hydrogen envelope, mass of which is about 0.5 percent by weight of the world. Earth originated about 4.6 billion years ago and about 4.5 billion years ago. It has manifested itself throughout the intense volcanic activity, which provided the earth's surface basaltic magma. Life originated in the boundary layer between high-density, but relatively cool hydrogen atmosphere and hot volcanic products - magma, ash and gases. Free water was not enough: it was on the hydration of silicate minerals forming serpentine and chlorite. The environment, in which life appeared, was represented by liquefied carbon dioxide pressure of gases dissolved in it. I imagine the emergence of life on Earth as follows. In the dark when the giant pressure hydrogen atmosphere of the planet's interior magma pouring out, an explosion occurs, emitting gases and volcanic ash. Hydrocarbons synthesized on a frozen lava or ash layer at a temperature varying. Polymers are formed of amino acids, sugars and other compounds - occurs before the film of life, which often breaks down with increasing temperature, but in exceptional cases, stored through the development of cooling mechanism. By selecting it passes all the stages of evolution and acquires the genetic code that allows collecting the polymer, capable of metabolism. Film life spread on the planet's surface and marked the beginning of the biosphere, the constituent elements of which continued to improve and create mats, similar to the modern. Their evolution took place already in the shallow pools. So, what factors contributed to the fact that among the inorganic nature could be life? First, it is the ability to form carbon and hydrogen, oxygen and other elements of the complex molecules in the combining polymers with thousands of atoms. Secondly, volcanic processes, which supplied gas, ash, magma and created on the surface contrasting temperature fluctuations. Third, the reversible redox reactions are accompanied by both absorption and release of energy. There were many other factors that contributed to the emergence and evolution of life on Earth.
