As for the Rosettes foldout, it can be nothing other than a representation of the medieval universe. Over time, I have set forth numerous reasons to demonstrate this. Naturally, human prejudices are powerful, and there will be those who do not believe me and hold a different view; however, they must substantiate their position and present a hypothesis that rivals my own.

I'm seeing a couple of logic/reasoning errors there.

Firstly, the "it can be nothing other than..." is an example of what's known as the Holmesian Fallacy (after Sherlock Holmes). In short, it could be something you haven't thought of, or something you have incorrectly dismissed.

Secondly, it absolutely is NOT necessary to present a better alternative in order to critique (or even reject) a hypothesis.
