A lot to explore there but, from what I gather of it, it's basically many different ways in which people have said, "I can't explain how anything can exist without God, therefore God must exist." I reject this statement. I prefer to state that, "Just because I can't explain how anything can exist without God does NOT mean that gods MUST exist, only that gods MAY exist."
One can have faith in anything, logical or not, realistic or not, and no one can prove that faith to be wrong. That does not, however, mean that your faith MUST be right. If you want to assert that your Faith is the truth then you must either provide evidence that it is true, or provide evidence that all other faiths, or lack of faith itself, is not true. If you want to assert that your Faith is a personal choice, I have no problem with that. Just keep it personal. Don't force it on those who don't believe as you do. That's all I, and most atheists I know, ask.
Religious institutions, on the other hand, are less about faith and more about conformity. They cannot survive unless all of their followers believe the same things. And in the worst such institutions, denying such dogma can result in death.
So please, keep your Faith, especially if it's the only thing keeping you from committing heinous act upon your fellow humans. But look very closely at the religious institutions and leaders which claim to be the true arbiters of faith. I'm quite certain that what you will find there will not in any way resemble the gods of your faiths.
