You: But it is an extraordinary claim. I am sure that you would agree that God is outside of nature, therefore he is beyond normal scientific inquiry and human understanding. I do not know what could be more extraordinary than that.

Aaron: I would not agree that God is outside of nature, for God is nature. God is part of everything around us, what could be more ordinary than that?

You: You are only correct if we assume that God already exists. If we assume that, then it is true that he would be as ordinary — that is to say, as common — as the air we breathe. But as it stands now, you are postulating an omniscient, omnipresent, immortal supernatural being of infinite power, and from my position there is nothing more extraordinary than that. So again I have to ask, where is your extraordinary proof that God exists.
