The various forms of life appeared on earth suddenly and fully developed, just as the Bible says.
Scientists have discovered that fire burns out, heat cools, energy is used up, everything decays, and life moves toward death. This discovery (known as the "second law of thermodynamics") argues against the theory of evolution.
Life did not develop by itself. It must have been created. It is easier to believe that God was the source of all life than to believe that everything created itself.
