Stump the Christian?

[abaris]

What evidence for God's existence could I provide that you would accept?

Well, you can question all of us. Jenny gave you some claims from the bible.

A  well observed supernatural event would be a start. Not an individual claim of one person, who I don't know and who could suffer from any kind of mental illness. Or simply be a fraud for that matter.

As some of us already said: Extraordinary claims require extraordinary evidence. And on a personal note, without knowing you, you probably would be quick to wave away any supernatural claim if it wasn't connected to your god image. Let's say having a talk with Bigfoot or, to stay in the god realm, Odin or Zeus.
