Evidence for a god. Do you have any ?

[polymath257]

Right, so if a supernatural exists, it *might* be a cause for physical things. But this is the opposite direction: it goes from supernatural to physical.

But that isn't the question I asked. I asked how the existence of something physical is evidence of something supernatural. To be evidence, it has to change the probabilities of the existence of a supernatural. How does it do so?

Because everything that exists did not miraculously come into existence the way it has without a source of knowledge and power. How could it possibly?

Knowledge isn't required. Stars are formed all the time without any knowledge input from anyone. All that is required is the action of the physical laws. As for 'power', that term is rather ambiguous in this context, but again, the physical laws are what mediate the formation of things.
But, and this is crucial, the known physical laws *do* allow for a 'universe from nothing', in part because the the total energy balance of the universe is zero (the gravitational energy is negative and exactly balances the energy from other sources).
