• Attempt to infer existence of God from observations about causation, change, motion, or related phenomena
• Where did the Universe come from? What caused all of this?

1. Everything contingent fact has an explanation (Principle of Sufficient Reason)
2. There is a contingent fact $C$ that includes all other contingent facts
3. Facts cannot explain themselves
4. Therefore: there must be a necessary being
