The universe will be dismantled an atom at a time. God will take each atom and make it vanish behind his Harry Potter Cloak of Invisibility.
When the universe has been dismantled an atom at a time and hidden behind God’s Harry Potter Cloak of Invisibility, God will then dismantle himself an atom at a time and hide the atoms behind his Harry Potter Cloak of Invisibility until the only thing left in the universe is God’s Harry Potter Cloak of Invisibility.
Sentience will evolve inside God’s Harry Potter Cloak of Invisibility and thus, God’s Harry Potter Cloak of Invisibility will notice a sizeable collection of atoms and decide what to do with them.
“Let there be light entertainment!” God’s Harry Potter Cloak of Invisibility will command and a new, slightly shallower universe will evolve.
And this is how God’s Harry Potter Cloak of Invisibility becomes God*.
And it is true because it has been written because it is true.
All: And so say all of us. Oh-oh, the hocus-pocus, that’s what it’s all about.
(from the Gospel According to Leif Garret)
*Although destined forever to live in a universe which refuses to acknowledge his existence, despite him once turning up at a fancy dress party disguised as a magic carpet with the words I’m God now and this magic carpet manifestation is a test of your faith woven into its fabric; unfortunately, it was in a language which nobody understood** and which looked like some fleur de lys patterns which had been stitched on by a one-armed bandit***.
** Only three people in the new God’s new universe could speak Cloak and they were all cloaks.
***Not a gambling one-armed bandit, but an actual one-armed bandit with only one arm.
