Religion is based on belief. Faith is not the same as facts. Theologians ask, if God wants the world to believe in Him, why doesn't He make Himself clearly known, why doesn't He appear in full glory so that no one could dispute His existence? The answer is simple. If God were to do that, no one would believe in Him. People would simply be forced to accept His reality.
That's why proof of God's existence not only isn't possible, it isn't desirable. If by proof we mean incontrovertible demonstration as a scientific proof would demand, then God will remain forever undiscovered. But if by proof we mean proving the most logical of two alternatives, neither of which can be ascertained as fact, then God can be "proven" as the more logical of two possibilities. A world with God has meaning, has purpose, has a way to explain its existence. To believe that the mathematical precision of the universe is the result of chance or coincidence requires a blind faith far more demanding than a religious disciple can muster.
