I will prove to you that God exists

Sure they do.

On the ‘fine tuning’ thingy, have you considered that it could simply be a happy accident? Suppose the universe evolved to support life incidentally. Out of a billion skillion universes, at least one was bound to reach a point where life-as-we-know-it could thrive. It’s a logical leap to presume that it was intentional.

And it's a logical leap to presume that the physical constants of our universe could be different. The fine tuning argument presumes they could all have any value and that their values are unrelated to each other to come up sith astronomical odds, but we have no way to know any of that. It's just a thought experiments with a lot of 'ifs' in it. Since when are thought experiments evidence instead of analogy?

Or consider this: what if working on the inverse-square, gravity falls off by the inverse-cube? That would imply far fewer stars and galaxies, but still some. Far fewer planets, and much smaller at that, but still some rocky lumps. Fewer goldilocks planets.

But even so, after fifteen billion years, we see a Universe more widely-scattered, with fewer black holes and galaxies and larger amounts of interstellar gases, but still with roughly 1/9th the amount of those platforms for providing environments for life to evolve.

Or maybe nothing coalesces enough for life to evolve, but the Universe still exists with no observers to document it.

I don't know enough about the other constants to project much.
