We don't kn ow this. We know that the universe as we know it had a beginning. What did, and did not exist before that, we cannot say with any certainty. For all we know, time, and space existed before the formation of the universe as we know it.
Yes we can say that with certainty.
We live in a universe which is governed by rules.
To say the universe was not created according to natural rules is ludicrous. There are even elegant mathematical equations which describe that process and they follow the rules of conservation of mass and quantum mechanics.
Actually, it's not ludicrous. In fact, a standing theory of physics is that the close you come to the event horizon of the universe, , the more the physical laws of the universe,
as we understand them, break down, and cease to function properly. So, there is every reason to believe that the universe came into being without being beholden to any of the laws of nature as we understand them.
Which is where inflation theory comes into the discussion. And according to inflation theory, space and time were created through a quantum tunneling event according to the law of conservation which must have existed prior to the event itself.
True, however, according to the theory, those "rules" are "leftovers" from the
previous universe, and prove nothing beyond the possibility of cyclic expansion, and contraction, and leads us no closer to this "evidence" of God.
Incidentally, please don't ask me to offer opinions any more technical than this. I admit I am
not an astrophysicist, and only have the most basic, rudimentary understanding of the theories. I only came across them when studying the Big Bang theory, and your absolute certainty that all reality "started" from there.
