I think the Christian idea of heaven is a fairy story, I certainly hope so. Some sort of afterlife might exist if the consciousness survives death,  but it is not likely to be a place where you sing praises to a deity forever, god help us!

If only this was a 'Christian' idea, T.  If you look at the Biblical record, this has little or nothing to do with what you are suggesting.  Biblically, 'heaven' refers to a variety of concepts, from a renewal of the earth to renewal of humanity.  The problem we have is that whilst Jewish culture used a lot of pictorial language in this area, the Greek that was used to express the same idea for 'Gentiles' is far more prosaic and literal.

Don't know if you have read Dawkins' 'The God Delusion', T, but I found myself agreeing with a lot of what he said, simply because the 'God' he describes in that book bears no resemblance to the God I worship or the God of the Bible: rather, it is the God that was created (largely) by the medieval Catholic Church to batter the people into submission to human foibles - the God who can be bought by the purchase of indulgences, the God who could be used to support human ambitions and greed, the God who could be guaranteed to prefer the rich over the poor.
