The explanation is simplicity itself: There is no evidence for the existence of any divinity. If I'm wrong, you can easily deomonstrate this by producing the evidence.
Second: The claim that "divinities explain nothing at all" is obviously false. For example, if a Creator exists, then we can explain the existence of His creation.
"If a creator exists ..." Well, that's something you need to demonstrate, isn't it? Until you do, you haven't explained anything.
Besides the bible? How about we are wired for God? How about the fact that we are built to worship. Everyone on this earth worships something. Whether it's science or religion, or material things. How about the research that shows prayer works. I realize to you this is "comic book" material, however, to many, it is evidence. Archeological evidence to support the bible, personal witnesses, but most of all to the individual, the peace that surpasses all understanding. I could go on, but what I've said already is futile. The logical mind is a blessing and a curse.
