@Leadfoot,
I love Theology done right because it is a challenge and so hard. Good Theologians are extremely rare and I would advise you to research a bit on what they say as it is extremely interesting even for an atheist like me.
Point being no a Mind of all minds could not create its own attributes ad nihile, from nothingness.
"God" being perfect and final could not change anything about its nature if you follow the rational. So it follows that if there ever was a mind of all minds it would be natural brut fact without any free will to change its own nature. Either it is Being or Non Being. Being being timeless has nothing to change or swap as it is complete throughout all spacetime.
In this vain God is more akin to a "rock" then anything else.
I also don't know what the frack "creativity" means...is one of those obscure concepts that stomps straight into the concept of all potential Qualia, or all potential Geometry and Maths...in sum all phenomena. It IS and its done...we discover what there is in Being we don't invent anything out of non Being...In common parlance from Nothing no thing ever comes! So "creativity" is just a pragmatical shortcut useful concept for our phenomenal experience within spacetime as humans.
