Might be closer to the truth than you’d think, though I could quibble on the details. (The good bishop got a little TOO speculative there, methinks.)
Why we should even expect to see the original 7 day creation world is beyond me. It had continuity with the Garden of Eden, which is now out of view.
We could call it a two-universe theory.
My own take on the 7-day creation is that days 1-5 took several billion years and days 6-7 took at least half a million years. Eden is somewhere in Mesopotamia where humans became self-aware.
