Extraordinary claims require extraordinary proof. That's the bottom line, if all you got is the bible that's not enough.
In order for me to believe. I would need you to pray to god, make it rain, but the rain came down in a checker board pattern, of heptahedral patterns, and the water did not flow but magically stacked up into towers of water defying gravity in symmetrically perfect heptagons. And then transmuted that water into rock and upon each pillar had fossilized inscriptions of I am the one true god in every possible language that had existed and will exist on this planet.
Then I'll believe. Because if all you got is a book that is filled with the same sort of impossible stuff as I just wrote up there, it's not enough.
