Given your premise that the conditions under which the universe originated were substantially different than the conditions we observe within the universe: Yes.
So either the universe is eternal or science is limited in what it can tell us about origins.
Well, that example is quite different from claim you were making. You were postulating the validity of instinctual assumptions in a scenario which you had just stripped off all foundations which our respective intuitions (or reasonings) are based on: Our concept (be it instinctual or rational) of causality is rooted in our experience of time and space.
The appropriate example would be rather: In the absence of distinct objects, would 1+1=2 be a possible, workable, meaningful statement?
I think causality and math are in the same boat. If nothing exists, there's nothing to count and nothing to cause, so neither idea is relevant or meaningful. But for spacetime to exist, both have to be there.
Well, you did. You talked about the absence of spacetime and postulated that causality is still a valid concept in this scenario.
Not quite. I said causality is a valid concept regarding the origin of spacetime. Causality exists simultaneously to the effect temporally, but prior in order of causation. That's true even in something like one ball hitting another.
Of course, at the point where you postulate that the unvierse came about in the absence of spacetime, you have abandoned your very axiom, in that your premise is exactly this: the origin of the universe isn´t related to the laws we observe to be ruling within the universe.
You can´t eat the cookie and have it, too.
When did I say the origin of the universe is not related to the laws governing it? That's the very point I've been debating against. Spacetime is synonymous with the universe, as I've been using the words. To say one came about in the absence of the other is tautologous. Either they came about or they are eternal.
I understand your inclination towards taking little jabs at atheism, but this has nothing to with atheism vs. theism. It affects any "explanation" for the origin of the universe - no matter whether it involves Gods or not:
We cannot postulate that a system itself isn´t subject to the conditions that are observed within the system (e.g.) spacetime, and at the same time demand that our "explanations" have to conform to the conditions observed within the system.
That´s simple logic and a question of consistency and coherence of our approach
Perhaps I misunderstood where you are coming from. I thought you were proposing the idea that the universe had a beginning but not a cause. That belief I consider an abandonment (partial) of science. If you believe the universe, (or multiverse, etc) is eternal, then I grant that is a logical possibility, and we just have those mathematical problems with an infinite succession to resolve, which I think may be possible. If the debate over whether the universe had a cause is resolved, we can go on to whether God, a preceding universe, or a multiverse is the best explanation; or if they are equal, we can move on to other things like the origin of life.
Was it science that convinced you that gods were real?
I've always believed in God, but when I started to doubt science helped confirm it.
If you go by that line of reasoning, then what should we make of the doctrine of creatio ex nihilo?
That spacetime and causality were first instantiated simultaneously. As ideas they eternally existed in God's mind. How mind can cause matter is a mystery, but something like it happens every day. A clear example is when someone gets an appliance with assembly required, and must read the owners manual to assemble it successfully. Information, processed by a mind, causes particular nerve impulses, muscle movements, and physical assembly to happen. One thing is for sure: God is a better explanation than the 'cosmic egg theory' mentioned earlier.
