Again, it doesn't matter if he's right or not. If he's right, then we have no way within this universe to disprove his premise 1, even when the evidence looks absolutely damning. If he's wrong, then the evidence is that things appear to happen within our universe without a cause, when the converse is exactly the basis for his argument from incredulity.
Okay, the phrasing just wasn’t clicking for me, but it has now. Yes, the quantum vacuum isn’t enough of a
nothing. I don’t see how this would mean that we have no way to disprove P1. Yes, it would mean that this quantum vacuum doesn’t disprove it, but the premise itself could still be countered by providing some other evidences of things popping into existence out of nothing.

The alternative premise (some things can pop into existence out of nothing) could conceivably be reasoned to from other observations (just like the KCA's P1 does). Or we could see things popping into existence with the best explanation being that the material there didn't give rise to it.

And atheism is actually a religion. Touché!
Why should we think atheism is a religion? And what does that have to do with what I was saying?
We should think everyone is a philosopher, including those who only trust science, because they are doing philosophy in doing so. To trust science alone to give us rational beliefs is bad philosophy. To trust logical coherence alone is also bad philosophy. I’m advocating for good philosophy, where philosophy builds off of scientific truths. And whether one accepts the KCA or rejects it, they are doing so through philosophy.
Since you didn’t counter what I said in favor of this, we can move on. Should you want to try to show the view you espoused earlier was rational, feel free to respond to what I said about it being self-defeating.

P1. Everything that begins to exist has a cause.
At your convenience.
I’m in another thread on the KCA as well, so I’m just reposting here what I posted there. I see three lines of reasoning to support premise 1 as the inference to the best explanation:
1. The idea that premise 1 is false is itself incredulous. Metaphorically, it’s worse than postulating a magic trick. It’s saying a magic trick exists, but without a magician performing it. No one believes things (universes or otherwise) just pop into existence for no reason whatsoever.
Off the top of my head, I think there are usually two reasons people disbelieve this premise. One, through a misunderstanding of some quantum interpretations (for this point I’m even assuming their coming to be is random and not simply unknown). Particles randomly pop out of the energy in a quantum vacuum is viewed as satisfying an uncaused thing beginning to exist, for example. However, this seems to me to misunderstand things. Virtual particles come to exist (even if indeterminately) because of the nature of the energy in the quantum vacuum. They don’t pop into existence for no reason whatsoever.
Two, is more ad hoc, as a way to avoid the conclusion of the KCA, usually by retreating to the need for 100%, which Historia has already done a wonderful job of arguing against, so I won’t rehash that. This is a very irrational reason to disbelieve premise 1.
2. Even assuming something could pop into existence and we just don’t know it yet, this would lead to an absurdity. It would then become inexplicable why anything else or everything else doesn’t also come into being out of nothing. What could it be about “nothing” that a universe pops out of it, rather than anything else? Nothing has no nature, so it can’t be discriminatory in that way. Neither would something else be able to constrain this “nothing” towards such an end because there isn’t anything there to constrain.
3. Common experience and scientific evidence confirm the truth of premise 1. Much of modern science is built upon this idea of causal conditions. To reject this premise would be to reject much of modern science, it seems.
Difflugia, your counter here was the following (I believe):
Difflugia wrote: ↑Thu Jan 09, 2025 2:40 pmThat's right, but it's a prerequisite. If we can predict it, there's an underlying cause. It's part of the filter: predictable things have a cause.
Okay, but this doesn’t mean that quantum events not being predictable (which is what we were talking about) show it to be causeless.
Difflugia wrote: ↑Thu Jan 09, 2025 2:40 pmSure, but it's evidence that things can change state without an apparent cause. There might be a cause, but the quantum explanations invoke the Uncertainty Principle and the fundamental randomness of the universe. If one state can change without apparent cause, then it's more likely that other states can do so.
Okay, but “nothing” isn’t a material state that could change without apparent cause; because it isn't a state something is in. So, P1 of the KCA remains the inference to the best explanation.
Do you have any further thoughts on these supports (or counter supports for an alternative premise such as “some things that begin to exist do not have a cause” or any other one)?
Still to get to in the future…
P2. The universe began to exist.
[William has brought up the need to define “beginning to exist” as This also might be where your article, William, would come into play, if it is trying to broaden the definition of “matter”, if not, it would come into P4.]
P3. Therefore, the universe has a cause.
P4. If the universe has a cause, then an uncaused, personal Creator of the universe exists, who sans the universe is beginningless, changeless, immaterial, timeless, spaceless, and enormously powerful.
[This is where a material cause such as William’s GOD or a leprechaun, would be knocked out of the running.
This only compares GOD and a leprechaun by them both being called “material”, not in any other way.]
