You forget 4) zero universe “4)” is logically implied by Mechanism (used by Darwin, and unfortunately (for them) materialist (making them inconsistent); All you need to understand is what is a computation. Then it is simple to show that all computations exists, and have a very complex subtle redundancy structured by the universal machine themselves in arithmetic. And that explains the appearance of a quantum multiverse, assuming 0 (physical) universe.
