The universal genetic code known as DNA, found in all living organisms, is firm indication of a common design of all life. The actual number of first organisms is not known, making the prospect of common origin not only singular, as God, the creator of life, initially created the first life to bioform the Earth, changing the surface, the seas, and the atmosphere to prepare the environment for the progression of more complex life that would follow.
DNA is the most complex information system in the universe, firmly establishing the existence of God, the creator, as no naturalistic process could ever create life.
