There's no reason why not. If the universe is contingent and caught up in a cause-effect chain, particularly an entropic one, then it's inevitable that there has to have been a First Cause. That's a mathematical absolute. So it's one of the few things of which we can be 100% certain.
I am very reluctant to be 100% certain about anything.
How about mathematics? Are you 100% certain that 2+2=4?
2 of what, plus 2 of what else?

Where's your attribution for that quotation? Did you expect me to believe it because it was typed, or were you planning to cite your source at some point?
I asked ChatGPT, and I imagine it references numerous sources. I didn't post it in the expectation, or even the hope, that you would accept it, but only in order to demonstrate what I accept.
Let me do better:
"The theorem proved in that paper is amazingly simple. Its proof does not go beyond high school mathematics. But its implications for the beginning of the universe are very profound. . . . With the proof now in place, cosmologists can no longer hide behind the possibility of a past-eternal universe. There is no escape: they have to face the problem of a cosmic beginning."
Cosmologist Alexander Vilenkin, Many Worlds in One (New York: Hill and Wang, 2006), pp.174-76
But you haven't done better, because I suspect you have specifically looked for a source that says what you want saying.

Yes, it can.
The "cycles" themselves cannot be part of an actual infinite regress of causes. So no matter how many one guess at (and now we're nowhere near empirical science with such a supposition), one has only pushed back the question one step: what started the cycles?
I obviously don't know how many people will agree with you, but I will be generous and assume it to be everyone in the whole world, except me, of course. Therefore, I will revise my statement to: it can't be known for sure by me that the universe isn't eternally cyclical.
IC wrote:Harbal wrote:I know that our understanding of logic says that isn't possible, but even if the universe did have an actual starting point, I have a feeling its origins will involve something our logic is unable to deal with.
Like God, you mean?
In principle, of course, but how seriously one would take that suggestion would very much depend on how "God" was defined.
Funny that that would be the only "something our logic is unable to deal with" that you'd deny was possible, even while embracing belief in "something our logic is unable to deal with" to replace Him.
Whenever I have referred to God in a conversation with you, it has been in reference to what I understand your particular concept of God to be, not any possible interpretation of what the word, "God", might mean.
IC wrote:Harbal wrote:My end doesn't have to be observed in order to know it is inevitable, because the process has already been observed countless times in entities exactly like me. Nobody has ever observed a universe coming to an end.
But you just conceded the point, anyway. You believe in something you haven't observed, on the basis of what you observe now.
You've lost me. What is it that I believe in that I haven't observed, on the basis of what I observe now?
