Can you explain this to me? It seems like an intelligent God Who intentionally created life would have had to design it. I guess if you believed that God guided evolution you might not consider it to be ‘design’ but it still would be. Using a process to design life would still be design. If you believe that life came about randomly, then God didn’t do it and Christianity is false.
God “designed” the laws of the Universe and set it in motion. Life evolved naturally based on those laws. That is why biology is so sloppy. A perfect God would have designed perfect life based on a perfect design concept. Our biology is a design mess.
