A Very Good Argument For God's Existence
Premise 1: What is truth or reality? A subjective, constantly changing uncertain thing which is indistinguishable from a virtual reality. Hume observed that just because the sun came up yesterday we cannot be certain it will come up tommorrow. Thomas Kuhn coined the phrase Paradigm shift for the way Scientific certainties can be overturned completely. In a Godless universe there is no absolute certainty; no universal reality; no objective truth. In a Godless universe, truth and reality are just words. Furthermore, if truth doesn't exist, how can you make the statement "God's existence is untrue"?
Premise 2: If God exists, however, then something exists which, being eternal and universal, we could call an absolute, universal, objective truth. If God exists, truth exists and if truth exists you CAN make the statement, "God's existence is true".
Conclusion: In a Godless universe truth doesn't exist but if God exists truth does exist. Thus the only truely true thing you can say is "God exists".
