whats life?????

Four and half billion years ago, the young planet Earth was a mass of cosmic dust and particles. It was almost completely engulfed by the shallow primordial seas. Powerful winds gathered random molecules from the atmosphere. Some were deposited in the seas. Tides and currents swept the molecules together. And somewhere in this ancient ocean the miracle of life began... The first organized form of primitive life was a tiny protozoan. Millions of protozoa populated the ancient seas. These early organisms were completely self-sufficient in their sea-water world. They moved about their aquatic environment feeding on bacteria and other organisms... From these one-celled organisms evolved all life on earth.1
