- Temporal things are temporal because they exist in space and time.
- Temporal things require an eternal cause.
- An eternal cause is eternal because it exists outside of space and time.
- Temporal things exist.
Therefore, an eternal cause of temporal things exists.
When we look back in space and time, we see a singularity that appears to come out of nothing because space and time were created in the beginning along with other temporal things. But since nothing comes from nothing, a cause must exist for these things. A cause that is outside of space and time is thus considered eternal, and thus, uncaused.
