Personally, I don't think humans will ever really, en masse, flock to the logic and reason the two of you prefer. Humans are creatures who prefer comfort, thought processes that are ingrained and easy to reference. They will prefer to remain shrouded in a fog, unwilling to abandon past superstitions, because there is no comfort or reassurance in logic. It doesn't matter WHAT religion you follow, the basic truth remains - humans vastly prefer an immaterial promise to material rationality.
Regardless what kind of logical fallacies you try to point out, or argument types you outline, people won't care. Simply because they'd prefer to believe they're going to a better place than this, they want to abandon their responsibilities and live according to a lawful decree that they are very familiar with.
And ultimately, its a pretty sweet deal. There is no "Christian Church" - there are so many sects and groups, you can pick and choose based on your own individual needs. So, fundamentally, human need and thought shapes the God they worship. In essence, it is their moral standard and ethic they worship. And they would prefer to believe there is an ultimate figure enforcing this moral ethic, than simply trying to live by it alone, because then, they wouldn't have anyone to implore for assistance when their morals and ethics prove incapable of handling a certain situation.
There are even those that are nondenominational, and live by their own interpretations of their holy book and assume that their god is aligned with the rationality and outcome dictated by their interpretation.
So, regardless what you try to frame your ultimate rationality and logic as, a large number of humans will simply prefer to live shrouded in mist of their own design, to assure themselves they have a higher power on their side, which agrees with their personal morality. It does not matter if its real, or provable according to reason or science, because they believe that their mind and belief makes it real and able to be experienced, because in their minds, simply finding solace in their personal morality makes it something able to be experienced and "proven".
If there is anything, ironchew and Art, that you've neglected, it is this truth.
