Whether or not you were indoctrinated in religion when you were young and impressionable, if you haven't experienced God the only rational choice is that the question doesn't matter.
As to indoctrination, I think you're putting way too much weight on that. One fellow I drink with sometimes was brought up in a strict Baptist family in Kentucky, yet he is absolutely convinced that God can't possibly exist. Another guy I knew was brought up by atheists, and had a religious experience when he was strung out and homeless.
As to "why Jesus" it's because of what he taught (The Buddha was certainly full of wisdom, I learned a lot about Buddhists when stationed in Thailand). Basically, love everybody. Treat folks like you want to be treated. Don't judge.
I don't think Jesus and Buddha would have had much to argue about except that reincarnation thing, and maybe karma.
