As an atheist I've questioned the religious beliefs of those who claim to be of the Christian faith to their face, in some cases and on other forums via the internet. They always get upset by being asked for proof of the basis of their faith and that I shouldn't undermine their faith by questioning it. If they truly believe in what their religion is based on, the fact I don't believe a word of it should have no effect on their faith, it doesn't say much for their faith that it cannot withstand a few questions.
I stopped believing in a god around the same time as I stopped believing in Santa Claus. If adults could consistently lie about Santa
couldn't they also be lying about a god? In fact there's more proof in the existence of Santa than there is in a god, as a child you could actually meet Santa and what about the presents on Christmas Day? The glass of sherry and shortbread for Santa, with carrots for his reindeer, were always gone on Christmas morning. He'd been there.
Then the doubts creep in, it can't be a lie, can it? But Christmas is supposed to be about the birth of Jesus, the son of God, so is that made up too?
Then it sinks in, it's all made up pish.
I don't dispute that Jesus existed, but the son of god? Nah. If someone turned up today claiming that to be true and just to believe him because he said so, he'd eventually be sectioned and be wearing a jacket with sleeves round the back. In fact the first people to attack him would be Christians because he'd be putting their faith into doubt.
