Everything in Jesus' ministry, and our lives as Christians, begins in the waters of baptism. How appropriate, since most evolutionary theorists hypothesize that water is the source of life. Not only did the first animals with a backbone have a common ancestor in first-like creatures, but the first life may have been one-celled aquatic creatures. More than likely, in ancient oceans there were chemicals which brought into existence complex organic molecules as a result of energy from the sun.
