Just to avoid that confusion: "certain" is not the same as "so incredibly sure that it would be world-shattering to discover otherwise", even though the former often is used colloquially to mean the latter. I'm pretty sure that that is some equivocation that's going on here.

So, you are saying that there is a claim that you are absolutely certain about?

Except there is no such thing. There is nothing in not being absolutely certain about anything that prevents you from still coming to conclusions and acting on them, and in many cases at least locally successfully so. There is nothing in reality, as far as I am aware, that guarantees that you can be certain about anything. And as such, you are simply demanding that I make an unjustified claim because that claim is an assumption that you want to make, and you maybe will refuse to engage unless I make that claim.
But that is not a problem that I can solve. I hold the position that absolute certainty is unjustified, and I am willing to help you understand that perspective if you are interested. You can either drop your assumption for the sake of the discussion, so you can maybe understand how my perspective makes sense, or you can insist that I should be sharing your assumption, which certainly will not allow you to understand my perspective.
In particular, you may want to take another close look at the examples that you used, apparently to try and construct contradictions from my statements. What you maybe want to pay attention to is whether those are actually contradictions (that is, self-inconsistent). It seems to me that many really just demonstrate that what I said contradicts the assumption of (the need for) absolute certainty. Which I'll readily admit they do. But that is not inconsistent, because that is not an assumption that I share. As such, they are expressions of how hard you find to accept what I said, which is fair--but they do not show a problem in my argument or reasoning.
