That statement right there disqualifies probably most anything anyone has to say as to proof. How so, you say?
How do you know Cleopatra lived? Or Alexander the Great? Socrates? Plato? There are no pictures or writings by these people saying "I (name of person) live!". And so what if they did. What proof is there that the person in question actually wrote it. What proof do we have that these people actually lived?
By the writings of others.
So when you say you do not believe the Bible, I could say that I do not believe the inscriptions and monuments of, and to, Alexander the Great, hence I do not believe he ever existed and is just a fairy tale made up to appease the masses, like Paul Bunyan, or Santa Claus.
When you start from a negative, closed-minded POV, why should I try to convince you otherwise. Sure, it's a challenge, but to my mind, you need to be dragged kicking and screaming to my POV and will probably work very hard at rationalizing away everything I say and do.
All I can do is give you the evidence and explain it. Only you can convince yourself.
That's all one can really do, grace has to take the ball after that.
