The universe's 'logic' (how it operates, whatever way that is) existed before we did. In fact, we were created from that 'logic'. We observed that 'logic' and said it was logic. The second we did that, logic was not of the universe, but our interpretation of the universe.
We created logic. The universe works the way it works. If you are trying to say that our logic is the same (exactly the same) as the way the universe works, you are being incredibly arrogant and setting yourself up for failure.
You're failing to distinguish between logic (the fundamental rules of reality) and logic (the symbols, syntax, words, and paradigms we use to describe the first context). We do indeed create the symbols, syntax, words and paradigms to describe logic but we don't create logic itself: it is external to us, and we just "map it out" like an explorer does to a new continent.
However, some logic we know absolutely. Identity, noncontradiction, and excluded middle are examples: not only do we know they are true, but we know that we know they are true (we have justification for our own knowledge of the knowledge, in other words: it is genuinely absolute knowledge... as in impossible to be false, contradictory to even assume could possibly be false, etc.)
Granted that doesn't get us very far. But it can't be said that we have no absolute knowledge. We do have at least some tiny specks; at least those who sufficiently understand logic do.
Once there was a time when our logic said that they earth is flat.
Not a statement pertinant to logic. Whether the earth is flat or round isn't a logical question but an empirical one. This is a VERY common mistake I notice: people confusing the contingent physical laws with logic.
That it was impossible to fly. That we couldn't get to the moon. That there is no life beyond our solar system.
Not logic, not logic, and not logic.
You can't say that any assumptions we make now, with our logic, are never going to be refuted. And if you agree with that, you can't say that our logic is the same as the way the universe works.
You're confusing logic with reason.
Logic gives absolutes, reason gives tentative truths that are subject to further evidence and refutation in the future. Logic is timelessly true.
