edge100, full respect to you for being the most challenging, incisive, thoughtful, and sensitive atheist thinker I have had the pleasure of personally chatting with. My hat goes off to you.

Therefore, the decision to choose one religion over another comes down to what evidence is available that supports the literal truth of one over another. If no such evidence exists, then my choice is clear: ALL of them are highly likely to be literally false. I'm not looking for the "least bad" evidence; is it more improbable that Jesus was born of a virgin, or that Mohammed ascended to heaven on a winged horse, or that a teapot orbits the sun between Mars and Jupiter?
It's pointless to get into questions about virgin births and flying into the sky if you don't agree with the more fundamental claims of any worldview, just as it would be pointless to try to convince someone of the theories of relativity who did not believe in science. Therefore, setting aside specific claims by any particular theistic religion, we can break down the general theistic claims about the origin of the universe and compare with what we have learned through the scientific method.
It is important to note, at this point, that there are 2 branches of science...operational science (empirical) and origin science (forensic). Operational science deals with present regularities, while origin science deals with past singularities. The crucial difference between origin and operation scince is that in operation science there is a recurring pattern of events against which a theory can be tested. In origin scince, there is no recurring pattern in the present, since it deals with a past singularity. Thus, the principles of each are different - operation science deals with repetition and observation; origin science deals with causality and analogy. The principle of causality is that every event has a cause, and the priniciple of analogy is that past events have causes similar to causes of like present events.
Since we are dealing with the origin of the universe, we will be using the priniciples of origin science to evaluate the claims of theistic religion. Theistic religion claims that the universe has a beginning point in time, was created
ex nihilo, and was brought into being by an uncaused, eternal, personal creator who sustains and can act within it in a super-natural way.
That the universe has a beginning in time is supported by evidence providied by modern science and mathematics - 2nd law of thermodynamics, expanding universe, general relativity, and the principle that anything that has spatio-temporal extent has a beginning and cause.
So if everything that we know to exist has a beginning, how did something come from nothing? What caused the big bang? We have no evidence to show that something can come from nothing without a cause. Science has shown us that the universe has a beginning, but cannot account for how it came into being. Of course, science continues to expand our rational understanding of the universe, but we are dealing with the present state of understanding, not our imagination of what may come.
Long before science came to its present understanding of the origin of the universe, theistic religion made claims about the universe that are in many ways in accord with modern scientific thought. Science mostly agrees that the universe had a beginning, but has not yet successfully postulated a cause. Whatver that cause may be, it must not have been itself caused, which means it must not have spatial or temporal extent, ie eternal. If this cause itself has no cause, then it must be pure actuality, since potentiality is a requisite for being caused, and thus pure simplicity, since it would have no possibility for division. It must also be immutable, transcendent of space and time, and unlimited in any qualities it might posess, since any limitation would imply potentiality, and thus negate its pure actuality. This is simply what the laws of logic and science tell us, but is also in accord with what theistic religion tells us, or hypothesizes, if you will.
If you are looking for evidence of there being a god, you have to look in the right direction....there's not going to be a "god" gene, or a "god" particle, or any way to "test" the existence of god in any sense that would satisfy science. At the same time, there are certain questions which science has gotten us no nearer to an explanation of. What caused the universe? What caused life? Evolution can somewhat explain how life evloved from life, but does not explain - in a way that has been proven - how life evolved from non-life.

And this is what I'm getting at....it is impossible for us to gather any evidence from before the big bang, which is a serious gap in our knowledge. Using the rules of logic, we can postulate ideas about what caused the universe, and those ideas add up to something that looks an awful lot like God.
To me the claims of theism make a lot sense from a rational viewpoint, and thus I cannot discredit the idea of the universe having a creator when that is a question science will probably never have an answer to. As stated before, the apples continue to fall while the matter is being decided.
