ORIGIN OF LIFE

Origin of life is still a mystery,as no fossil records survive. Nobody has synthesized life  from non-living matter. But scientists have progressed so far  that we have begun to understand  how life began. On the basis of verified facts and probabilities, it is thought that the life originated through a process of evolution. About five billion years ago when the earth was very hot, it had hydrogen, nitrogen , oxygen and carbon in the free elemental  forms. As the earth cooled,simple compounds, of these  elements such as methane,ammonia and water vapor were produced. The molecules were held as thick as clouds,then some of water condensed and came down to the surface as continuous  rains. The great seas were formed,the ultraviolet radiation from the sun and the frequent lightening helped to form several other compounds in the  atmosphere devoid of molecular oxygen. These chemicals as well as various minerals and salts form lands and reached the seas. The molecules mixed and collided with one and another. Sometimes two or more compounds fused to form larger compounds like simple carbohydrates, proteins,fats and nucleic acids. Such  molecules slowly organised themselves and formed small aggregations. These bodies acquired the essential properties of life,growth,metabolism and multiplication. Gradually cells and simple organisms evolved. In some such way as this, the living matters seem to have come into being in primeval sea water. The earliest records of the life occurs about 3 billion years ago.
NATURE is working in small ways but the result is bigger. I think NATURE IS WILL of GOD working for HIM. Now one can see sea changes around the world and worried about these changes as we have mixed our WILL and worked on it. World is extending and extensions are destructive in some ways as it is interfering with NATURE. We are doing so as thoughts arises in our mind to know the unknown and it is human nature-keep in mind to keep balance of thoughts always to serve humanity and GOD EQUALLY.
