Hmm. I listen to death metal pretty frequently (crazy fact: I stumbled upon this forum for that very reason!) but I think I am a believer in God.
Experience has shown me that there is a very definite way that things happen to be, even though we can convince ourselves that whatever we're dealing with is very different than whatever might actually be going on. Sometimes I think this tendency is very natural (what we could call hubris in this context) because it has probably helped us out a lot as a species. The ability to forge ahead against daunting odds, and the willingness to take on arbitrary challenges, is no doubt a useful cognitive feature for staying alive and sharing knowledge with the upcoming generations. It probably did take quite a bit of bold odds-denying thought that got us to where we are today as a species.
Anyway, that theory of mine came from thinking about why we (or some of us) are inclined toward the idea of gods in the first place. They are like archetypes that we can look toward to give us motivation and courage to act righteously even in the face of defeat. That is how we got around obstacles in the past, and we still apply that ability constantly though at a smaller scale.
Another quick theory of mine (buckle your seatbelts; this gets a little Freudian) is that neuroses develop when one of our sruvival instincts is overdriven. For example, America has a load of fat people, because fatty food (high in sodium, carbohydrates, high fructose corn syrup, maltodextrin) is really satisfying and easy to come by. In the past, humans were lucky to find fatty orr sugary foods. Now, it is so abundant for us, that we are unable to consciously curb our craving because it was a very handy evolutionary feature in the past. So compare this example (laterally, so much as you can muster, because it relates to a general biological process rather than a neurological or psychical process) with our need to find a supernatural explanation for occurences (superstition) and you might have an idea of what I'm saying.
With the help of science, we now understand more about the way things like our bodies and brains work on a very basic level. The same with weather, stars, and animals. This understanding has removed much of the "childish" magic of explaining things like consciousness, love, space, etc. Still, we are inclined to believe in that sort of magic, because it is the way we understood things when our species was like a child. It ois the way things are put together in our brain from pure observation, without any abstractions like quantified weight, speed, pressure, density, distance, time, or whatever else we can apply an objective value to. Those nummbers don't really matter to our brains, which have their own way of storing information. To bring this post back to the topic, the means by which we come around to God is the way he brain stores information a out the unbendable rules of the universe around him. Hubris might let him test the actual bendability of the rules, but God will always be there to remind him of how far rules can actually bend.
