I only pose the question because of the trillions upon trillions of examples that have existed throughout history, none of the observable examples would support the "always was" category. Well the only proposed answer to that question that I know of is God...
Plenty of theoretical physicists have hypothesis' that overall existence always was. Its not new at all.
Asking for examples inside of a finite singular universe - though - is a catch 22, everything observed inside of THIS universe is finite but we haven't OBSERVED outside of this universe to even address the question.
To simply state that there is a branch of science that poses a theory that "somethings" always were, without any evidence to support that theory while simultaneously rejecting a contradicting and similarly non-provable theory, is not a sound argument.
Actually, if I may interpose something, it's not unreasonable for one to assert that an ontological materiality may have always existed. That's one of the two ultimate options of origin: materiality or transcendent immateriality. And as you correctly say, it's ridiculous to presuppose materiality and reject the other out of hand. What's the grounds for that? Nothing but the presupposition of materialism, which is not scientifically verifiable at all and never will be, anymore than transcendent immateriality is currently scientifically verifiable.
The truth of the matter is, objectively speaking, if God does exist, as I believe He does, the latter has a better chance of becoming scientifically verifiable were God to ever "pull back the veil" that currently blocks our natural senses from perceiving the transcendental realm directly than the prospect of us ever affirming the eternal existence of the quantum vacuum from this side of it! That's a think about it for awhile epiphany!
But let the materialist assert that, as what I wrote elsewhere, the foundation for understanding the real issues of origin, stands; these facts of human cognition cannot be brushed away
:
Folks are turning the ABCs of a very simple matter into rocket science. Everybody with a sound, developmentally mature mind knows or apprehends these things about the problems of existence and origin:
The Seven Things
1. We exist!
2. The cosmological order exists!
3. The idea that God exists as the Creator of everything else that exists, exists in our minds! So the possibility that God exists cannot be logically ruled out!
4. If God does exist, He would necessarily be, logically, a Being of unparalleled greatness!
5. Currently, science cannot verify whether or not God exists!
6. It is not logically possible to say or think that God (the Creator) doesn't exist, whether He actually exists outside the logic of our minds or not (See Posts 2599 and 2600)!
7. All six of the above things are objectively, universally and logically true for human knowers/thinkers!
Those are the facts of human cognition regarding the problems of existence and origin. The objective facts of human cognition report, you decide. God just might be waiting for you on the other side of that leap of faith. There's plenty of rational and empirical evidence for His existence. Take the leap of faith now or don't. It's your decision, not mine.
All the rest of the things I've talked about go to the apprehensible details of
#4. Not everybody can follow that or will even try because they've made up their minds about things they know nothing about or have never thought about.
But what all can and should logically understand, that which is self-evident, regarding
#4: to assume that the reality of the construct of God would be anything less than the very highest conceivable standard of being unjustifiably begs the question. From an objective standpoint, finite minds are in no position to rationally presuppose anything less, as such a thing would necessarily be an apriority of a purely subjective standard of belief. An objective standard presupposes nothing less than infinitely unparalleled greatness and, therefore, absolute perfection.
It doesn’t matter that we can't comprehend the totality of that. We can and do apprehend the meaning of a highest conceivable standard of perfection whatever that may entail. In other words, logically, nothing created could be greater than the Creator of all other things, and what is the highest conceivable standard of being in this regard
: an eternally and transcendentally self-subsistent, i.e., non-contingent, sentient Being of infinitely absolute perfection!
Earlier it was wrongfully asserted, in my opinion, that the objective standard was not biblical. Well, goody, but even if that were true, that would be the interposition of a purely subjective standard of belief that is not going to wash with any person who recognizes the objectively uncontestable standard that doesn't beg the question. In short, objectively, it's the only standard that leaves the matter open-ended without any conceivable allegation of preconceived bias.

Note: Both the Bible and the objectively apparent facts of human cognition strongly recommend that God is a Being of infinite greatness/perfection.
