You keep saying the universe is impermanent and this is where I disagree. It cannot be. I agree that everything within is. However, the universe cannot pass out of existence, then back into existence without a creator. Once it passes out of existence there is nothing. Nothing is absolute. Something (the universe) cannot come from nothing of its own volition.
Hmm. I'm gonna have to come back to this from another angle. Let me see if I can approach it in a different way.
All phenomena arise from ever-changing relationships with other phenomena, including the minds of the observers. I am concerned with HOW things exist, not IF and WHETHER things exist, or WHY things exist, such as God, the devil or the spaghetti monster made them.
1) The universe consists of myriads of particles in a constant state of movement.
(2) These particles form aggregates which hang together for a time and then disintegrate.
Nothing whatsoever remains identical from one moment to the next. All 'things' are impermanent, and so all things are in reality processes. Things do not stay the same from one millisecond to the next. Anything composed of atoms is composed of parts in a constant state of flux. Existence is merely impermanence viewed in slow-motion.
Because this is how the universe exists in continuous motion, we can say it is transient, not permanent.
We cannot say that we as human beings inherently exist;
(1) An inherently existing entity exists in splendid isolation without the need to reference any other entity. It is completely defined by its own nature.
(2) An inherently existing entity is uncaused.
(3) It is indestructible.
(4) It is eternal.
(5) It is unchanging when viewed externally.
(6) It cannot undergo any internal changes of state.
(7) It either has no constituent parts, or if it has parts those parts are inseparable.
(8) Consequently, nothing can be ejected or removed from it.
(9) Nothing can be added to it (this would change its definition).
(10) No change in external conditions (up to and including the destruction of the entire universe) can affect it.
God may be a candidate for an inherently existing entity, but if he were truly inherently-existent he could never undergo a change of state in response to external conditions (eg become angry at sinners/infidels and send plagues, pestilences, shaheeds etc to destroy them). Neither would it matter to him whether he was worshipped or not, for no external factor could in the slightest degree affect him.
Also, if God is omnipotent, he has the power to destroy everything, including himself. So even God must be empty of inherent existence because his continued existence is contingent on his not committing suicide.
