OK, let's try again from another angle.

God[s] is/are supernatural, subject to no rule of nature, and wholly unconstrained. His/their "existence" is not the kind of everyday existence you and I can comprehend, but something other entirely. To try to use science, or even rationality, to support a view that there is no god is utterly pointless. Science is concerned exclusively with the natural and has nothing - absolutely nothing - to say on the matter of gods. Likewise, it is impossible to conceptualise the nature of gods, so it is impossible to disprove them by rationalisation.

If you don't believe in god, you can only support your stance by saying it is mere opinion based purely on faith and instinct.

As for scientific theories of creation, they fail in one important aspect: they stop short of the moment of creation because they can find no scientific explanation for it. And they jettison all known science in order to explain the Big Bang as far as they can understand it. Nothing can move faster than light ... yet the universe would not be as it is now were it not for the inflation period ...

According to science there's not enough matter in galaxies for gravity to keep them together, and they should be spinning apart ... but for the effect of dark matter. Yet no-one can find any dark matter or say what it is, although it should be the most plentiful substance there is

Science does not even know what reality is in the natural world - we may only be reflections of (or in) a quantum mechanical universe. How, then, can it even begin to address questions about the supernatural?
