Thanks! I'm aware of that, my point was a little tongue-in-cheek pointing out that just because we don't know why something works doesn't mean it can't be the answer. You said it best by saying that it is "outside our accessibility" how are there many parallel universes? How do we know? What caused the big bang? Why does it exist? We simply don't know the answers yet so we can't throw out any theory just because we can't fully understand/explain it yet.
