"One compelling reason not to believe the standard-issue God exists is the conspicuous fact that no one knows anything at all about it. That’s a tacit part of the definition of God – a supernatural being that no one knows anything about. The claims that are made about God bear no resemblance to genuine knowledge. This becomes immediately apparent if you try adding details to God’s CV: God is the eternal omnipotent benevolent omniscient creator of the universe, and has blue eyes. You see how it works. Eternal omnipotent benevolent omniscient are all simply ideal characteristics that a God ought to have; blue eyes, on the other hand, are particular, and if you say God has them it suddenly becomes obvious that no one knows that, and by implication that no one knows anything else either."
