Swivel:
Does not containment imply container? When one discusses a void "containing" anything, this seems to imply spatial extension. Yet if it is a void, it is meaningless to consider it having spatial extension, no? As space itself is not a property of "void".
Moreover, can we speak of an absence of something as rightfully producing a consequence? For does not this require something acting in relation to nothing? How can one react to nothing? Isn't that "not reacting"?
Consider also that an acausal cause of causation implies causality prior to its establishment. Accordingly, it would seem that if causality exists, it exists eternally, for it to come into existence requires it to be caused.
You are thinking of things taking place in an empty universe, with time rolling along, it seems. You are taking the ideas of causality that we know to be true from within our universe, and applying them to a non-universe. This is jarringly illogical to me.
All hypothetical, but logically consistent:
There is nothing in the void. There is no time elapsing. The first thing that ever happens, the first moment, is the sudden creation of matter. This happens as a result of the incredible (let's call it "Sucking Power") of the void. That doesn't mean that anything is IN the void. That would be like saying that there must be something in a vacuum region since it has Sucking Power on its surroundings. The Void is the same type of a thing. It is nothing, but it has properties. One of these properties is obviously that it contains nothing. Another property is that time does not elapse. Let's say that another property is that the incredible Sucking Power of the Void is so great that it sucks matter out of nothingness. Not "from" somewhere. Not "into" anywhere. It is just ex-nihilo. The power of the Void is so great that matter must rush into being, with space (and time, naturally) right along with it.
That is the logical creation event that I posit. Why is this superior to an eternal creator? Simple: It gets rid of the logical contradiction of an eternal past. It also gets rid of the need for a chain of causality. It seems obvious to me that there must have been a time when nothing existed. But this state wasn't eternal, because there was no time elapsing. So the first moment was instantaneous, a necessity, a foregone conclusion. And the clock has been winding down ever since.
Why does it seem obvious to me that there must have been a time of nothingness? Why couldn't there "always" have been matter around? Because that assumes a *fulfilled* infinite past, which is impossible. And even if it were possible (which I stress, it isn't), matter would have run out by now. We would have a cold-death of the universe already. Why? Because if energy and matter can NOT be created ex-nihilo, then nothing could replenish the energy lost due to entropy over an infinite past. Even with oscillations of big bangs and big crunches.
The only way around this makes it even worse, you have to posit infinite matter and energy to go along with your infinite past (again, impossible). But if there was infinite matter which existed in a way that it has the ability to interact (needed to replenish the losses due to entropy), couple this with an infinite past, and we would have had the final collapse of everything an infinite amount of time ago.
There is no way around creation lore, both secular and parochial, unless you toss causality out the window. So, start there and see where it leads you.
