(Reflecting on Poul Anderson's "Requiem For A Universe" and SM Stirling's Emberverse.)
(i) God creating universes.
(ii) An uncreated universe with a Mind evolving in and surviving the end of that universe, then influencing the evolution of subsequent universes.
(iii) The Mind of (ii) time travelling and thus becoming the "God" of (i)?
(iii) does not conform to theistic belief.
I still argue that the creator before the creation would be a self without an other which is like a square without sides, therefore that (i) is impossible.
