But it does.
The sun does rise and set, contrary to what is written in the main faq.
Here is the global Piri Reis map with latitudes:
Rotate the tropics of Cancer and Capricorn by 23.5 degrees, and we get the upper and lower bounds for the orbit of the Sun on a flat earth.
It rises from beyond Japan and illuminates at least half of the entire surface (not a spotlight sun at all), and sets somewhere beyond Antarctica (just like in the Black Sun photographs taken by F. Bruenjes).
Then, it rises again to complete its orbit over the other half of the semicircle (approximately).
This is the correct description for the Sun's orbit on a Flat Earth, the one that should be included in the official FAQ.
The most important part of the Sun's orbit is its precession (the westward shift of 1.5 km/year).
Now, the word "sets" needs careful consideration, depending on which part of the year we are talking about.
The depth to which the Sun reaches the towards the shores beyond Antarctica differs according to season, of course, as can be seen in these videos.
