Aaaah! Another advocate of the theory of coevolution! Perhaps you can tell us how that theory works (other than to say it works, other than to say 'because I am an atheist and the answer to a question can never be God'). Another person on this thread seemed to believe in that novel theory but was totally unable to explain it. Perhaps you can do better. Of course, if you claim it is science, you will need to give scientific proof of it, a few examples of macro-co-evolution would be nice.
