According to the study of earth, earth came into being some billion years ago. At that time temperature of the earth was too high, but at later stages it cooled down.
It's a fact that steam condense into water that result into the formation of oceans. Scientist believed that the gases like helium, hydrogen, ammonia and water vapors were present at that time. According to scientist all these conditions existed before the creation of life on earth.
Now if we consider what the main requirements for existence of life.That are for sure first unicellular came into existence. So, logically for survival oxygen, water, salt, protein all these things must be present. A specific range for survival of life is required. It is believed that after cooling of earth organic matter had been formed. Such a simple cell has capability of reproduction as well to prepare food for its own existence. That cell must contain enzymes, nucleic acid, fats around it. All living beings are contains protoplasm's that's a living matter. Our body is composed of different cells, which are of different shapes and sizes. Each cell is responsible for the function of its organ. The cells are composed of both organic and inorganic matters.
