Most anons know about things like gyroscopic progression.
Others of us know why the sun "dies" for three days in December because we know what apogee is.
If you want to account for all of these things, for the flower petals of "Venus", the motion of Neptune, etc - then go ahead and incorporate that into a flat earth model. The problem is that your solutions must become arbitrary. Venus must move in the way it does because … Someone designed it to do so. Just an arbitrary doodle of god. The sun rises in the same place for three days because… Why the fuck not?
Rather than a harmonious system wjere these patterns are emergent from its rules and laws, they simply become arbitrations of a weak and small minded entity who couldn't engrave them as part of a larger system.
Your god is small and inferior next to even a human's mind.
