The Contingency Argument is probably the best proof of God’s existence. When we consider the universe, there are three ways to explain its existence: It either has no explanation, it is its own explanation, or it needs to be explained by something else.
The third option — the heart of the Contingency Argument — is the most plausible of the three.
Here’s why.
Introducing the Principle of Sufficient Reason.
To say the universe has no explanation seems to violate the Principle of Sufficient Reason, which states that when things exist, we look for the reasons why they exist.
This principle governs our lives and all scientific research. When you come home to spilled milk on the floor, you know there’s an explanation. The milk didn’t suddenly appear there. The same is true with science. Scientists don’t approach an experiment exclaiming, “This chemical just happened for no reason.”
