LoftyLottie, the fact that I cannot prove that there is no God is of no importance or significance. When similarly challenged, Bertram Russell pointed out that he could not prove, either, that there is no china teapot in solitary orbit around the sun, but that is no indication that there is such a teapot.
Similarly, I cannot prove that there are not invisible fairies at the bottom of my garden, but until somebody gives me reason to suppose that there are I am entitled to assume that there are not. Why? Because the idea makes no sense.
The idea of God makes no sense. It is a supernatural concept. He, she, it is supposed to do magical things. So the onus is on believers to offer some evidence that this unnatural being exists. If they can't then I am entitled to assume that it doesn't.
Well, so far, no-one over the millennia since the Jews invented "God" has anyone ever produced the slightest smidgeon of such evidence. So I stand my ground.
