all those infinite different possibilities are within the confines of an eternal universe of potentialities.
if there are 5 dimensions, ours stemming from one of them.. then those dimensions are part of the universe, and where di they come from? what caused their existence? quantum fluctuations that cause dimensions, strings, matter and energy to pop into existence from nothing? go back to the quantum fluctuation that created the dimensions and strings and mass-energy... go before that.. there existed the possibility for quantum fluctuations.. and that possibility always existed.
no matter what the origin and cause of the universe, it is eternal. it has always existed. or it was created at some time. if it just "popped" into existence, then that potential for things to "pop into existence" always existed. if it did not, what created that potential ? what created that ?
maybe 60 trillion years ago 20 dimensions were popped into existence. our being one of them. before that there was nothing but the potential for something to pop into existence via quantum fluctuation or whatever. if you went back another 500 trillion years or so, there was most likely another 20 or 30 or 50 dimensions in which many universes existed and eventually dissapated into nothingness and pure energy. and before that, another few hundred trillion years of nothingness except for the potential for things to pop into existence... another universe.
no matter what the state of the universe, either it has always existed, or it was created at some time.
the question is, which makes more sense, an eternal and self caused universe, or an eternal being that created the universe? if you get out of the theological box and think of god more like a pantheist does, that the universe itself is God, having a mind of its own but no physical body except the power to cause things to exist and create life.. belief becomes easier.
the idea that life just popped into existence in a universe of lifeless mass-energy is a whole other conversation, but its one i feel is much much more conducive to realizing the most probable existence of God.
sure, what type of pantheism are you suggesting, it appears sentient so i assume its not actually pantheism you are suggesting, you are confusing pantheism with pandeism as you are not suggesting the buddhist stance or spin of the belief. Pantheism in an idealistic sense, is a type of consciousness that exists not sentience but instead it is the opposite of monist physicalistic pantheism.Pandeism makes the claim which exerts all is sentient, which is what you are suggesting i take it? that god is everything and this thing is a sentient being creating things, pantheism makes no claim like this.
also, from the post below are you talking about existence or our universe? because its likely that our universe is a son of another. If this is the case then it can be imagined that our logic may not apply is parent universe, that perhaps the laws of physics do not follow causation, as such, your question is irrelevant as you can only use your logic which could very well be constrained to this universe. You see you are making assumptions that do not exist or require your presuppose them. For example your question demands causality, you are saying this is here what created it, because you do not have the answer you claim something that needs no creator (god in your example) created it. You are skirting around the same old argument.
your grasp of the word eternal is also lacking, i do not mean this in a rude way, i like you
but if the universe has always existed ie eternal it never was created, it has no creator, and it's essence like aquinas said is to exist. Also, causation is a macro physical problem, thus your question is based off experience at your level, which you deem is true reality, however, at the quantum world causation does not comply, thus your need for everything to be eternal or created by god is meaningless. THUS IF THE UNIVERSE IS ETERNAL THE POTENTIAL FOR IT TO EXIST NEVER EXISTED BECAUSE THERE WAS NEVER A STATE IN WHICH IT DID NOT EXIST, THUS, THE UNIVERSE REQUIRES NO CREATOR, IT REQUIRES NO EXPLANATION, IT HAS NO BEGINNING, NO END, NO REASON, PURPOSE OR CAUSE. Therefor i hold the position that energy is eternal (which converts to matter) and has always existed, hence matter can neither be created or destroyed, it always existed since it existed.
but say im in another universe, it could be matter pops into and out of existence for no reason, or cause, from no potential etc, that is just as likely in physics as matter not being able to be created.
