Evidence for a god. Do you have any ?

[Deesse23]

You would never assign two time coordinates to the same exact arrangement of matter in the universe.

Why not?

The flow of time is not determined by a human being assigning time coordinates. Time doesnt care what humans think of it. Just because nothing (noticibly) changes and noone writing down time stamps while time goes by, doesnt mean time doesnt go by. You are putting the cart before the horse. Time cares for the existence of space (since we know they are bound together) and the presence of gravity. I can imagine a black hole in otherwise empty space, determining the flow of time within its gravitational field, and the order of matter (within the singularity) remains as is. In fact thats whats possibly going on right now in the vicinity of the supermassive BH in our galaxies center.

Let's imagine an immaterial being existing in a state of complete changelessness with absolutely nothing else in existence (a possible world if you will).
Tell me, is there a passage of time?

Sorry, first you must establish that this immaterial beings´ existence is possible, before you proceed to "possible world". Something is only possible after you demonstrated it is possible.
Otherwise:
#1 lets imagine an invisible, pink unicorn farting rainbows and thus creating universes.......
#2 universes do exist
#3  

Let's imagine the same being then has a thought about something. And subsequently has another thought. How much time has passed between the only two changes?

Until you demonstrate that your premise is actually (or even potentially) true: "immaterial beings (can) exist", i reject any of your conclusions as unsound.
