That is the issue, to assume "it is a nowhere cycle", "that we don't know" is a fallacy by itself. You base your entire reasoning on certain axioms without the slightest proof, from which you then start your reasoning.
If I don't know something, that just means I'm lacking knowledge which I can then fill with knowledge using deduction, evidence, and reasoning. Correctly ascertaining that we don't know the full scope of our world isn't something I say because I have proof of something, its because I lack proof of me knowing something.
That is not how logic works. You presume something to be self-evident and true that isn't at all. You basically foretake the conclusions through your faulty logic.

Except, not really. Honestly, it seems assumptions are being made about me which honestly is just evidence further to my overall point.
My whole methodology is to use evidence to back up my views. For instance, I don't say people are biased because I think people are biased. I say people are biased because there's history and research and evidence to back up the idea that people are indeed biased through their life experiences and genetics. It's not self-evident that people are biased. There's support backed up by real life examples that people are biased. That's logic. But its also logic to know that your current logic can be proven wrong, cause there's evidence of that happening before.
I merely took that logic of people being biased and expanded it outward to a more cosmological idea; a thought experiment, not something that accurately portrays my views, but as an idea of an overall concept of humanity's propensity to believe in only what they see even if it may not be the case in the grand scheme of the universe.
Instead of asking yourself whether your questions and premises are valid, you jump to there are no answers and we cannot know based on a faulty methodology.
Again, it seems like assumptions are being made about me which doesn't in any way reflect my actual process. My methodology is to find evidence of something, and if there's evidence pointing to something, its then time to explore to see if that evidence points to a bigger, repeatable idea. At any time, with the addition of further proof, the idea can be bolstered or proven to be wrong. To be skeptical of our current understanding of reality and to be aware of missing details and the fact that we don't know everything is how logic and science can boost itself forward.
If you want proof that we don't know everything, explain to me why gravity exist? Not what it does, not its relation to time, but why it exists at all in our universe? There's no definitive answer as to why and how gravity exists, but just because we don't have an answer doesn't mean there isn't an answer out there.
Also proof that our logic can change at any time? People used to believe lobotomies were a good method for treating the mentally ill. People at the time believed that to be true, but later evidence and treatments proved them to be false. Just because we live in modern times and we're alive right now doesn't mean that some of our evidence that we gathered for certain ideas can't be wrong. We're realistically just as clueless as the people of the 30s and 40s, only we don't perform the lobotomies now cause of our understanding of our world has changed.
I think this'll be my final point right here cause I'm starting to get tired of this.
TLDR: Logic dictates that that evidence is needed to make an assumption, but there's also evidence that logic can be proven wrong, so its logical to be skeptical of current logic. That's how progress is made.
Also, why are you writing a whole sci-fi monologue in this forum? You can write your novel in the main website (just kidding, I'm sorry.) And how come this whole thread sounds like a conversation that some scientists might have before doomsday arrives? I'm little concerned about this foreshadowing.
This entire thread did kind of get out of control. Honestly didn't mean that, just wanted to put out something I was thinking about recently. Also, funnily enough, this topic literally is basically the entire plot to a Sci-Fi story I've been thinking up.
