After all your vitriolic protestations against the idea that we might not know everything, and that some of what we might not know might have a bearing on the subject under discussion, you recently posted on your other thread:
Living with unanswered questions is human. What we ought to avoid is pretending to know things we can't know.
If our belief is commensurate with the evidence and beyond that we can say, "I don't know" we are being reasonable.
