No one has observed speciation, despite watching millions of microbes. The connection seen in DNA may not be a sign of heredity. It is only speculation. It cannot be proven, If DNA is basically a blueprint then you would see the same specifications for similar elements. All Mott and Bailey castles have the same basic design but they were not all built by the same person. The heredity theory was derived from the belief that evolution exists. it is a theory to prove rather than a proof of a theory. IOW you are /were looking for the connection rather than discovering them. The eye sees what it needs to make it logical. But Optical illusions look very real.
TOE can never be proven, And God.'s hand is not always obvious. Science cannot see or believe in God so no scientific theory will ever include Him. ToE is aetheistic. I am a Christian . .I will believe that God created the Heavens and the earth. ToE says nature created itself. My god is not a spectator. My God is not resting, or worse dead.
