I think you did a noble thing, LR, in separating this debate into the two different arguments - the moral and scientific reasons for or against God's existence. We cannot draw implications of one set from the conclusions of another.
Scientifically I just don't really know enough to argue for or against different minutae of our knowledge of the function of the universe. Dr Watson said that the more we learn, the less useful God becomes as an explanation. I know what he means, but I think he is extrapolating a MORAL implication (We should abandon the idea of God) from a scientific conclusion (For instance, God is not holding up the Sun). This is dangerous. In a similar way, eugenics erupted as a moral implication of evolutionary theory.
But to blame all evolutionists for the Nazi's depraved excesses is to make a scientific implication (Evolution should be disregarded) from a moral conclusion (exterminating races of people is bad).
There are two concepts of God that sometimes get confused in debate threads like this: God as benevolent (a moral concept) and God as Creator (a scientific concept).
So - what does this mean for our debate? I propose we take this in a new direction, following the above guidelines - science cannot provide morals, and morals cannot provide science. Therefore, scientific knowledge, or the lack thereof, does not prove or disprove the notion of God as benevolent completely - it merely explains a function of our universe. Neither does morality, or the absence thereof, prove or disprove the notion of God as Creator. You can only use morality or its lack to prove or disprove God's benevolence. You can likewise only use science to prove or disprove God's creative input.
These are the new rules I propose, in order to help further clarify and define our debate.
