Shim, there is no evidence for or against.

Only half-right. Certainly there's no evidence for. We have only assertions. The evidence against is very strong on an intellectual level. An eternal, all-seeing, all-knowing, all-powerful God is proposed as the explanation for the universe and everything in it. Just think, all those clusters and galaxies and stars and planets and the laws of physics that govern it all, much of it so complex that, as yet, we have no more than rudimentary knowledge of it (though we're closing in, thanks to scientific endeavour). That being so, the God who created all this must be infinitely more complex. Yet no-one has ever seen this fellow or been in touch with him. There are no traces of him anywhere. The proposition is for a infinitely complex being whose very existence trumps every law of nature yet for who there is not a scrap of evidence, just assertions. Religion tries to explain the universe in all it's complexity by installing a being who, himself, is deliberately put beyond explanation. Disturbingly, more and more of his "creations" can be explained, as time goes by, by resorting to no more than the laws of nature. God isn't really much of an explanation at all, is he?

It is not supposition but a fact that, if God exists, He would be outside and above the laws of nature that He would have created.

It is neither a supposition nor a fact. It is an unsupportable assertion that, conveniently, puts God beyond arm's length from science. That is religion's deliberate ploy, intended to make God invulnerable to intellectual scrutiny. Where God is concerned, only blind faith can reign supreme. Critical examination is not permitted. Religion, in the way it chooses to define God, sees to that. I've seen more honest approaches, frankly.
