Allow me to start by clarifying that I am not a man of faith. I don't presume to know whether or not there's anything more to this existence than what I've observed, or even to know whether what I've observed is reality.
So assuming that the assumptions that sincere, Christian prayers backed by honest faith don't work is correct (and I know quite a few Christians who'd vehemently disagree based on experiences they've claimed to have had) and you've proved that the bible is fallible, how does it follow that you've disproven the existence of even the Judeo-Christian god? Consider the possibility that despite claims to infallibility and 100% divine inspiration, the bible, being written by man, is in fact riddled with mistakes, but that a good deal was actually inspired by the divine, which happens to be the being that, for the most part, the bible describes as God. I won't argue the likelihood of this scenario by any means, as I'm not a believer myself, I simply draw this illustration to point out that this proof that God is imaginary leaves doubt, even where Christianity is concerned.
The greater question is this: Assuming that this was undeniable proof that Christianity is false, how does that then disprove the existence of any god? There are infinite potential explanations for existence. Even if you had managed to strike one down beyond the shadow of a reasonable doubt, how does it follow that you've disproven every explanation involving a god?
As a side note, this burden of proof argument that keeps happening between the religious and the atheists is the silliest shit ever. The only way you're not making an assertion is if you accept the possibility of either (that there is a god or that there is not). If you say, there is a god, you've made an assertion and the burden of proving that assertion lies with you. If you say there is no god, you've also made an assertion and the burden of proof for -that- assertion lies with you. Quit trying to pawn your responsibilities off on each other, you lazy zealots.
