Here is a post from Michael Dowd's blog:
The crux of the problem, as I see it, is the failure of millions of people, religious and non-religious alike, to distinguish meaningful metaphor from measurable reality. God as a subjectively meaningful interpretation simply cannot be argued against. God is always a legitimate interpretation. But God is NOT (and never has been) an actual, physical Being, as science and common sense define reality. (Those who would attempt to argue that God is a REAL Father or King, but just in an unnatural, otherworldly sense are left in the bizarre position of claiming that God, the Creator of the Universe, is less real than the Universe, as I discuss here.)Many believers and atheists alike define God as a being among other beings, spiritual in nature but still a being, who also happens to be super-powerful and possessing infinite resources. But God is not a being. God does not belong to the same ontological category as you and I. As soon as you stop thinking of God as a being then much of the debate between atheism and faith ceases to make any sense. This gets back to Tillich's conception of God as Being Itself. If you instead think of God as the foundational interpretation of reality at its deepest and most fundamental level, the whole question of "proving" a supernatural being's existence becomes moot.
HERE IS A WAY OUT OF THIS IMPASSE: Whenever you hear the word ‘God', think ‘Reality'. "I have faith in God" can be translated "I trust Reality". "God is Lord" means "Reality rules". Throughout the world, God has never been less than a mythic personification of Reality as a Whole, Ultimate Reality, or what today some call "the Universe". If we fail to recognize this, we miss everything. ALL images and characterizations of God are meaningful interpretations of Reality As It Really Is. When we forget this, we will inevitably trivialize God, belittle science, and desecrate nature.
