Martin, I'm not sure you are doing justice to dismiss the question of God's existence in favour of science etc. Surely it is equally open to question the whole ridiculous hypothesis of who God revealed "himself" to. I'm sure I heard Pell say last night that revelation stopped with Jesus and that he came from an ignorant bunch of farmers as opposed to the intellectually superior Egyptians and Persians.So the idea is that God created the world , let it go for some time then destroyed it again with Noah then let it go till he again revealed himself with Moses and then later with Jesus and the Apostles. Not once did he consider venturing further afield to Asia, Africa, the Americas or Australia. And from out of this came a dogma which will give you an eternal life if you follow the Church's interpretation. I should also add that last night Pell also gave a free pass to anyone of any religion provided they were good so what's the point of following the Church's dictates.
My point therefore is we should still go after religious dogmatists for their own stupidity and their imposition of dogma which is counterproductive to the good of mankind until such time as science conclusively proves what sane people already know - the universe evolved out of a big bang and we should make the best of our very limited time here.
