I don't know if this applies to either of your thought processes but as a "round earther", I'd like to present this event: https://en.m.wikipedia.org/wiki/Discovery_of_Neptune
Neptune was discovered only after it's location was mathematically estimated with gravimetric equations.
Uranus was discovered in the same way right before. These equations do not work with a flat earth model
