Science is something I can and do believe in. I'll take what can be concretely proved over what can't, any day of the week.
That said, I do reserve a bit of reverence of a sort (for lack of a better term) for what cannot be determined through strictly Cartesian means (i.e. deconstructing a thing into its component elements, on the belief that the larger thing's functionality will become evident through said deconstruction)... it was Douglas Adams, I believe, who noted (quite truthfully) that, "[i]f you try and take a cat apart to see how it works, the first thing you have on your hands is a nonworking cat." There is something that is inescapably metaphysical about life itself and how it comes about, at least in this world at this time, and I have a sort of respect for that -- an understanding between me and the universe, if you will, that there may be something that science can't explain that's going on there.
But that's really about as close as I get to religion or faith. Organized religion, quite honestly, seems to me an exercise in podiatric self-marksmanship (if you'll forgive the euphemism) -- if the point of the whole thing is to bring you closer to God, why put structure and organization and the inevitable middlemen that such things bring with them, in between you and Him...? It simply doesn't make sense to me that, in order to speak to God, you have to go through something to the effect of a human bucket-brigade -- which sounds like an open opportunity for things to go like a game of Telephone, amongst the other disadvantages.
