Lilygran, you say:-
"I think this is where the tolerant secularist and the believer have to part company. As far as we're concerned, matters of faith are matters of fact. Do you want us to say, 'this is what the religion teaches, but of course, it isn't true' ?"
No I don't, but I would hope you to be able to admit that even for you it cannot be more than a matter of belief, for surely a matter of faith can ultimately only be a matter of belief? A verified fact ceases to be a matter of faith.
As an atheist I do not believe that there is a god, but I cannot prove it any more than Richard Dawkins can, and I do not expect science ever to be able to prove the existence or non-existence of some kind of supreme being or originator of the universe. At it's most basic, who lit the touch paper for the Big Bang?
