For a while there was some ridiculous evangelist who toured college campuses to debate evolutionists and he came to my campus. One of my professors at Berkeley was a paleoanthropologist, studying evolution and dinosaurs, and my favorite exchange to summarize my views of the utility of Intelligent Design versus Evolution was this comment he made that completely stumped the evangelist.
He pulled out a book of dinosaur fossils and alligator remains and said roughly, "this is my life's work, I can't say I've answered life's great questions, but I have added to the understanding of the fossil record and better our knowledge of alligators and their history. You have your Ph.D and your formal education, but what have you contributed to human understanding?"
And thats the summary of it, Intelligent Design and the usage of religion to answer questions of physics has adds almost nothing to our understanding of physics, evolution, or biology.
There have been many great religious theoreticians and thinkers, but the usage of religion to answer the questions of physics has always been shortsighted and quickly discarded.
Thats why asking what created oxygen is different from who created God. Asking the questions of physics leads you somewhere and improves your understanding of the universe, but going into a religious breakdown of physics leads you absolutely nowhere.
