Referring again to your analogy, there is nothing in the room that suggests the presence of God. What I've tried to point out respectfully is that God, as the beginning and ending of all things in the theological universe, must be assumed as already existing to be proven. We can surmise that the gorilla broke the vase, or we can explore other possibilities within the material universe.

I'm comfortable with not knowing all the answers, and I don't think religion adequately describes the world around us. To invoke God as the reason for everything simply isn't adquate in the absence of what I consider to be proof.
