While the current topic of discussion at Getbig Theological Seminary seems to focus on whether one can prove God's existence, by asking the question and, then, proceeding to parade a bunch of morally evil individuals as some kind of counter-proof, you are committing a fallacy. Subsequently, what you have actually brought into question are certain attributes of God (whether real or imagined), namely, His omnibenevolence and omnipotence. You haven't touched upon His existence per se.
