There are methods to treat the validity of the theory that a God exists and created this universe.

[Roger Penrose:]

“Try to imagine phase space… of the entire universe. Each point in this phase space represents a different possible way that the universe might have started off. We are to picture the Creator, armed with a ‘pin’ — which is to be placed at some point in phase space… Each different positioning of the pin provides a different universe. Now the accuracy that is needed for the Creator’s aim depends on the entropy of the universe that is thereby created. It would be relatively ‘easy’ to produce a high entropy universe, since then there would be a large volume of the phase space available for the pin to hit. But in order to start off the universe in a state of low entropy — so that there will indeed be a second law of thermodynamics — the Creator must aim for a much tinier volume of the phase space. How tiny would this region be, in order that a universe closely resembling the one in which we actually live would be the result?”

[Lennox:]

“His calculations lead him to the remarkable conclusion that the ‘Creator’s aim’ must have been accurate to 1 part in 10 to the power of 10 to the power or 123, that is 1 followed by 10 to the 123rd power zeros."

[Penrose:]“number which it would be impossible to write out in the usual decimal way, because even if you were able to put a zero on every particle in the universe, there would not even be enough particles to do the job.”
