God is not an impossibility. The problem for God and his advocates is that he is, by any stretch of even the wildest imagination, extremely improbable. Nothing in nature is inexplicable. Much in nature remains to be explained, but we are closing in, and the endeavour is wonderful. But as soon as you insert that dismal copout of an "explanation" for everything, in other words God, you are sidelining that wonderful thing that you might have expected the God-squadders to laud above all other human attributes, our intellect. You can't believe in God and also be entirely rational. Not that being entirely rational is always a great thing, as we are not all Mr Spocks, and a good thing too. But to have your life, your behaviour, your relationships and your moral compass all based on an irrational notion is a bad thing. Just think it through. Nothing you see in nature cannot be explained by natural laws, and whatever we have yet to understand will one day be explained once we understand those natural laws better than we do. But God is above natural laws. He is supposed to explain all of nature and the laws that govern it, yet be not just above nature but also against nature. All-knowing, all-seeing, all-powerful, no beginning and no end - all these supposed attributes are counter to nature. But the real clincher is that there is absolutely no evidence for his existence. Not a scrap. But that doesn't mean he doesn't exist. It just means that he's about as likely as a duff bottle of Hirondelle. I'm an atheist and I don't know whether God exists or not. But I'm not what you might call fifty-fifty.
