The third argument I offer for God’s existence in my “Does God Exist?” podcast series is the Kalam Cosmological Argument. This is my favorite argument for God’s existence.
The argument reasons to God based on the temporal finitude of the universe. The essence of the argument is that temporally finite things require a cause for their existence. Since the universe began to exist in the finite past, it also requires a cause. An examination of the properties required of such a cause match the properties of the theistic God.
