Our reasons for believing Jesus existed and also that He was who He claimed to be - the God who came down - are the same reasons for believing any fact of history: the documentation is substantial and it passes all the tests of historical reliability. Scholars - both liberal and conservative - overwhelming agree that Jesus of Nazareth was a man of history and the Gospels, on the main, tell His story accurately.

Almost everyone agrees the world is not the way it ought to be. It's called the problem of evil.

The word "Christian" means something in particular. The basic outline and general truths and doctrines central to Christianity have been hammered out over 2000 years of reflection on the teachings of Jesus and his apostles. If you disagree with these foundational concerns - the kinds of things I focus on in The Story of Reality - then you're simply not a Christian.

An alternate explanation is not a refutation.

Reality has a way of injuring people who don't take it seriously. If you don't believe in gravity, for example, and then step off a tall building, you won't just float away.

If the Christian doesn't get reality right, he loses effectiveness in this life. If the non-Christian doesn't get reality right, he loses much in this life, and everything and the next one. As Jesus put it, "What does it profit a man if he gains the whole world and loses his soul?"

If the Story is not accurate to reality, it's not any kind of truth at all. So it can never be 'my truth' or 'your truth,' even though we may believe it. It can only be our delusion or our mistake or our error, but it can never be our 'truth.'
