Tsk Tsk Tsk, what a mess we make when we begin with assumptions based on illusions.
Firstly:
big bang creating/causing itself,
god creating/causing universe,
brain creating/causing consciousness,
mind creating/causing choice,
is all predicated something coming from nothing and are therefore impossible. Therefore I do not need to waste my time reading any books based on those illusions, and getting lost in details that are all based on false beginnings, like you have.
-We currently have substance therefore it must be uncreated and eternal.
-We currently have motion therefore it must be uncreated and eternal.
-We currently have order, therefore it must be uncreated and eternal.
Build your conclusions or science from and within those absolute starting points.
Secondly:
Don't assume the universe or the brain continue to exist when you're not looking at them. The only thing that's proven is this consciousness here now, as it is here now, and nothing else. Any other belief just happens in consciousness here now. A belief in the universe, the brain, matter, all happens in and of consciousness here now and therefore proves nothing except for consciousness here now.
Build your conclusions around that absolute starting point.
Consciousness is not in the body the body is in consciousness,
Consciousness is not in the universe, the universe is in consciousness,
and it must be eternal.
So you see my good sirs I AM the creator of the universe.
