I will prove to you that God exists

My 'bias' is the result of 'the astonishingly narrow parameters of certain characteristics of the universe, and that if they altered even a vanishingly small amount, then the carbon life we know of, could not have emerged'.

Can you cite a scientific result showing that any of these characteristics could vary?  (Rees' book is a popularization, but if you can quote where he claims that they could vary and backs it up with citations, that at least would be a start.)

What would be your explanation that if a universe comes into existence unintentionally by mindless natural forces, that it 'has' to be in the same exacting narrow configuration that allowed life to occur in our universe? If it were so and we could observe other universes with the same properties, laws of physics, stars, planets solar systems it would only leave us to believe universes are caused to exist to produce life. It would be the same explanation why motherboards are identical, because they are intentionally caused to be identical.

Lastly, why would I have to prove Martin Ree's (and many other scientists) belief in multiverse theory? You don't seem to realize this is a naturalistic theory to explain how the universe we live in hit the right properties for life to exist.
