I think I get your thesis now. Science will progress until everything is knowable. There will be no "room" left for a God in the explanation . . . .Everything in the Universe will be shown to have a physical or natural explanation. No supernatural explanations necessary. Then you apply Occam's Razor and say it is a simpler to explain that the entire Universe just exists this way, than that it has a Creator?
I don't fear scientific discovery. I think it would be interesting if we could understand everything about the Universe and how everything works. We are curious creatures, mankind, aren't we?
I see two ramifications of the above thesis. First, it would seem to be hard to walk the line between being agnostic, and having a type of "religious" faith in science, until that day down the road when everything is proved. Science is conservative, and scientists do not rely upon things which are not yet proven (or at least without having explanatory theories for which some evidence exists and/or which haven't been refuted by contradictory evidence). Until then, putting "faith" in the possibility that it will (no matter how high you place the probability), is still "faith" and not science itself . . .The above thesis is still in the realm of metaphysics rather than science. Having "faith in science" is still faith and not science . . .
Second. Even if the entire Universe and everything in it were to be scientifically explained, that would not prove that it was not created. God is by definition outside the Universe: outside "time and space." He still would be. Fundamentally, you can't prove a negative.
We would have this entire marvelous Universe to appreciate with even greater awe. I am already impressed by the unexpected beauty of fractal geometry, the unexpected determinism of chaotic systems. Who knows what else is out there, for our edification and delight?
Recent science has generated renewed discussion about intelligent design; the anthropromorphic principle is intriguing; I need to find time for some more reading -- I am getting further behind just thinking about it . . .
Intellectually, you might say, well why bother? You still don't "need" God. Why have this type of Santa Claus in the sky, just to hand out sugar plums and switches for good and bad behavior, etc.? Well, I'm adding this so you may have an appreciation for the way some other folks think. They could say: Not believe in God? Of course I believe in God. I know Jesus. Jesus is a friend of mine . . . There is a lot more to people's relationship with God . . .
