If God has a hand in the affairs of men, then why is it so hard to believe that God also has a hand in the affairs of animals?
God is the creator and author of the universe. If, as the Bible says, God knows the number of hairs on a man's head, and that nary a bird can fall from the sky without His knowledge, then why can you not accept that God also might have a hand in forming the traits of animals over a long period of time?
Where does it say in the Bible that God created animals which will never change one little bit?
