> AFAIK, that question is still ultimately unanswerable beyond what would be just semantics. Out of my range of expertise but I think this could be said about all knowledge. For instance, about elementary particles, You can always say, "What if there is one lower level that we can't detect?" And the right take-away is not: "Therefore, we never know the cause of anything." The right take-away is that "causation" has to take into account contextuality. You can make lots of X causes Y statements that are valid, as long as you specify the context. The second example is relevant because it's another illustration that knowledge is contextual. Though it's not about causation. The connection is that I'm trying to use the contextuality of knowledge to defend causation. So I was giving a "pure" example of the contextuality of knowledge that doesn't also involve the complexity of causation.
