There is currently absolutely no empirical proof of god/creator that can be proven to people who are non-believers because all current claims of a supernatural deity rely on claims of faith, revealed religious books, and belief. Trying to use the bible as proof of god is prototypical circular logic. "The bible is true because the bible says or I believe that is is true"
