Need a new thread, guys.
Space and time (thus causality) are an aspect of the Big Bang, that is, they are created. They don't exist before the Big Bang. Einstein helped show this.
There is no space and time and thus no "logical" causality (IN OUR time-based view, that A...B....C) before the Big Bang. By that I mean logical causality or sequence IN OUR SENSE where we would have to say that something else also had to create God first (ie. an infinite regress of cause and effect, where something always creates something else like a bottomless pit, never ending). That sort of causality is part of space and time only, AFTER the Big Bang. What is before that (outside of space and time) and how it works, we can't understand. Once you get to the edge of the Big Bang, the A...B...C question is not answerable with our way of thinking (science/sequence etc.), because it implies a sequence in time (and space), which don't exist. That is where faith comes in.
God must be outside our circle of causality/universe (outside of space/time sequences), and not subject to them. He is outside the universe of space and time. Some higher dimension. Always been the church's view, as has creation out of nothing from Genesis (the Jews got it right and were the only ones in the ancient world to think this: it took till this century to prove it, Hubble and a Catholic priest mathematician, Lemaitre, who convinced Einstein of this, etc.).
These things are mysterious, a bit like a Cray computer trying to run on rice crispies as the operating language.
The clincher for me is that reality is mathematical. Quantum physics (the best and most accurate science; the greatest achievement of the human mind) is pure idealized math where the smallest subunits of reality fit numbers exactly. Why should reality be like a math equation, granular, fitting whole numbers? It should really be random and chaotic or just a big nothing, a big fudge. It's not. It's totally finetuned and mathematical.
NB: mathematics fitting the physical world is not a placebo effect (like a rabbit's foot), but something pre-existing and a priori. It does not depend on our minds. A very rough analogy: VO2 max does not depend on your psychological state at the moment: it is set largely by genes, after being trained a bit. It's a priori.
But there's also freedom for us. That's another question.
Any way, nuff said. I REALLY apologize if I've offended anyone. This is not the place for this.
