I watched an interesting program on TV yesterday (called "Testing God") that looked into the progress of science and how science has managed to explain more and more of reality to such an extent that a belief in God is (almost) redundant.

For example, they've even managed to explain how the big bang could have happened without needing an "instigator" to start it off.

But, the final question remaining that scientists still can't explain (and maybe never will) is this: Why do the laws of physics exist in the way that they do.

The laws of physics are "just so" so that it enables life itself to exist.

Must God have been the creator in the sense that he designed the laws of physics or is there some other explanation that doesn't need the existance of a supreme being?
