Any evidence at all that is testable and can stand up to peer review. I don't think that's too much to ask.
So, basically, you ask to not need to have faith in anything. You ask for a concept that doesn't exist for any belief system, including atheism (you have to have faith that coincidence occurred in just the right ((implausible)) way, etc.).
The problem with what theists assert is that it simply assumes everything is accurate in the Bible with no skepticism or corrboration at all.
Ever been in space? Then how do YOU know that the world is a sphere? You see pictures, you hear stories, you read about what other people say and why they say it..... How's that any different?
Let me ask you this. If someone came around today and said, "Wait. I was born of a virgin. I'm the real messiah." would you believe him?
I'd say it was unlikely; you believe because you want to, but not because these are facts that have been in any way corrborated. They haven't been. They've just been stated, and a lot of people uncritically believe them.
In no way does that make it true.
I agree, it doesn't make it true.
Hell, the disciples were all there, watching what was going on, seeing and living the miracles. (yes, I know this is all according to the numerous books that make up the Bible, but go with me here) Even after seeing it all, when Jesus was killed they went back to fishing (at first - and yes, I know they weren't all fishermen.... go big flick with me). They had, by all the stories, all the reason in the world to pass out from sheer wonder at all they saw, and they just stopped wandering with the guy 'cuz he died, so they went back to work. That's always been a sticking point for me. But, that doesn't make it NOT true.
So, if a person came up and claimed to be the
real Christ, I'd need some proof. If I witnessed a few miracles, I'd probably write 'em down (and, Xa, I'd probably not care much about when his birthday was). I may believe, I may not, who knows. We're probably more cynical now than a couple thousand years ago.
But, you're right. I believe because I choose to, as you choose not to believe and have faith in something else instead.
