Halcon: If you can accept that there is an aspect of reality that cannot be seen, heard, touched or even proven..which are our thoughts and emotions, which are the most real parts of ourselves, then it's not a stretch to believe in the existence of God.
I believe that god may exist, since my limited understanding of physics makes the origins of the universe seem fantastic either way. I do accept that those who have advanced physics degrees appear to make sense of it, but to me it sounds like magic. Even this approach requires that I am ignorant of the science, but I suspect I am like a great many people in this.
If this god does exist, then this universe is most likely an experiment of some kind. This being cares about us only as data; it doesn't care about us as individuals, nor does our survival concern it at all. It launched a universe, it is learning from it, and at some point the experiment will end.
This short and simple concept fits our current universe and our current world just fine. It answers many of the difficult questions without creating any of its own (aside from the obvious one). Once we go down the road of describing this god through a holy book, there are expectations that must be met. If there was a god that cared about our outcomes --as individuals or as a race-- it must make itself known. The fact that no religion is able to convince even half of humanity that their god is the right one --to say nothing of the differences within any religion-- makes the idea of such a god untenable.
