Kalam Cosmological Argument for God's existence

Mike articulates the Kalam Cosmological Argument: Premise 1 — everything that begins to exist has a cause. Premise 2 — the universe began to exist. Conclusion — the universe has a cause. He argues the cause must be external to the universe (not self-caused), and must be spaceless, timeless, immaterial, and incredibly powerful. He adds the cause must be personal because it chose to create. This leads to a description matching the God of monotheism and Christianity specifically.
