Im sorry but Im finding it difficult to answer you in this form. However, Im sure Ive picked up on the main points below, but if theres something you feel I should have answered, but havent, please post it again and Ill answer by return.
I said the only thing that can exist prior to the action of anything being un-causally caused is something that is unconditioned, upon which the conditioned depends for its existence. You replied that it sounded like I was supporting your argument. In one sense thats true, because fundamentally were arguing the same point, which is that something exists from eternity that explains what there is.
The concept of Supreme Being has never exclusively meant a worshipful being, deity or a property of religion or theism, but an entity with the power over all things as an explanation for life itself.
The premise is that matter doesnt actually create matter: it is self-existent, and that is to say eternal. The essence of matter enables changes in shape and form, separates, increases and decreases (what we call cause and effect) but is not destroyed and the world continues notwithstanding. It reacts and changes according to the laws of the universe, which in turn are governed by the concept of its necessary existence.
Now please explain where God is to be found? I say that God, as transcendent, personal being who seeks a relationship with humans is a purely arbitrary notion and one that is not without contradictions. You are arguing from something that is proven to exist in order to infer something that cannot be proven to exist, against which there is no argument that informs us that matter, which is real and existent, has not always existed in some form or other. Gods existence can never be proved by inferential arguments, but only by ontological ones. In other words the argument should be God, therefore the world, and not The world, therefore God.
