Well I would word it differently, for example does the bible contain any objective evidence that a deity exists, or is even possible, since the word proof in this context is something of a misnomer, and welcome to AR.
I would say that if the bible does contain any objective evidence for any deity, then I can say I have not yet met, spoken to or read any theist or religious apologists who demonstrated this.
You mean in your hypothetical book obviously, not the bible, as we know it contains erroneous claims.
Well the bible contains some factually correct things, and it contains bare claims about supernatural events, derived from an epoch of extreme ignorance and superstition. The way I decide which claims are true is by insisting they be supported by sufficient objective evidence. Again I have not seen anyone demonstrate any for any deity or anything supernatural, or even that they are possible. Thus I remain disbelieving.
The Spiderman movies accurately depict aspects and events in New York, this doesn’t make Spiderman real.
