God's existence is either true or not. But calling it a scientific question implies that the tools of science can provide the answer.

Religion is unusual among divisive labels in being spectacularly unnecessary. If religious beliefs had any evidence going for them, we might have to respect them in spite of their concomitant unpleasantness. But there is no such evidence. To label people as death-deserving enemies because of disagreements about real world politics is bad enough. To do the same for disagreements about a delusional world inhabited by archangels, demons and imaginary friends is ludicrously tragic.

There may be some deep questions about the cosmos that are forever beyond science. The mistake is to think they are therefore not beyond religion too.

Just because science so far has failed to explain something, such as consciousness, to say it follows that the facile, pathetic explanations which religion has produced somehow by default must win the argument is really quite ridiculous.

If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!

When I am dying, I should like my life taken out under general anaesthetic, exactly as if it were a diseased appendix.

It sounds superficially fair. But it presupposes that that there is something in Christian theology to be ignorant about. The entire thrust of my position is that Christian theology is a non-subject. It is empty. Vacuous. Devoid of coherence or content. I imagine that McGrath would join me in expressing disbelief in fairies, astrology and Thor's hammer. How would he respond if a fairyologist, astrologer or Viking accused him of ignorance of their respective subjects?
