So extinct species represent what? Failures of the Creator? I don't think so.
Maybe failure of your theory? Species were designed to fail?
Ask a theologian, I do not claim to know God's will. I am talking scientific facts, not religion. Explain euglena, the platypus, the wasp, the bat, the Cambrian, the butterfly in an evolutionary way. You claim evolution is science, then defend it in a scientific way. Do not change the discussion to a religion which you do not understand and do not believe in.
