"Show me just one valid supernatural event and I will gladly believe in spirits, demons, and magic, however, for me to believe in the God of the Bible you must first prove to me that every comment and event in the Bible is true."
My standard for proof of "supernatural knowledge" is exactly the same
for the Bible as for modern day psychics, mediums, and prophets.
They would have to demonstrate clear, unambiguous preknowledge
of a non-common event, documented before the fact, with a high
enough ratio of correct details to false that I know they are not
just shotgunning plausible guesses and getting a few right.
I have not found even a single convincing case of true prophecy
in the bible that can stand up to reasonable critical thinking.
Of all the claimed prophecies in the bible, I have found that they
all fall into either the category of vague enough to be stretched
to fit, or without any good evidence that they are written BEFORE
the events they purport to predict.
So yeah, if there was even ONE prophecy in the Bible that was proven
to be ONLY possibly via supernatural intervention, I would be convinced
that SOMETHING supernatural interacted at least once with Bible writers.
Of course,, why should that supernatural information provider be god?
Maybe it was a demon, who made the prophacies come true later.
Maybe it was time traveling aliens. Why should it redeem the rest
of the book as a reliable guide, seeing how filled it is with things
which are at best wrong, and at worst dangerous?
How would I tell the difference between the true and false aspects of the bible?
