The First Question of religion

I guess the first question regarding religion would be the question as to whether there exists a God or not. There is a first obvious answer, and that is that it is not possible to decide one way or another. Obviously, if there were an easy answer, there wouldnt still be a debate. Most people have come down to saying that Science cant prove or disprove God, and some even say that it shouldnt try.

But the closer I look at this question, the clearer it becomes to me that not only is the existence of God unprovable either way, but that it seems that the question is designed to be unprovable. What I mean by that, is that you get wierd things like the ability of meditation to give you experiences that are consistent with seeing God - boundlessness, a feeling of infinite love, ecstasy and so on - but this can be explained by science as the deadening of several brain areas that deal with defining the me/universe boundary, and so on. So you have a spiritual experience that can hypothetically be explained by science, but it seems coincidental that the brain on meditation would give this effect, and not simply send you to sleep, say, or give you horrible feelings. Why does it just "happen" to give you spiritual experiences? Most things are like this - they give god-answers, which can be explained, just enough to disprove the god-proof, but never enough to dismiss them entirely. Faith, it seems, will always be required, as proof will never be found. Yet there will always remain enough grounds for faith. Curious coincidence that. Just curious enough.
