I'm not concerned about whether you were misled about a specific viewpoint, I'm just trying to clarify the viewpoint you're presenting. The thread is pretty long and it's easier just to ask for clarification than read the entire thread and maybe miss something.
To be clear, are you saying you believe the earth is essentially a flat square (and yes, I get that "a flat square" means something that has hills and valleys based on a flat square, rather than thinking the existence of a hill disproves the flat earth theory)
If by "earth" you mean ground (not sky/firmament), then something probably similar to a square, perhaps more rectangular (ie: footstool). Necessarily, East and West have no "ends" in this idea, so one does not travel to the "edge" as there is none. However, North and South
are met by boundaries - ends if you will - that we cannot go beyond. I have no idea exactly what this might be, but I do know it's not possible for the average person to go past certain points, and this is by international treaty. A rather curious thing, that. I wonder what they found.
All the difficulties encountered by the AE or circular flat model, insofar as sunlight times and direction are not a problem with a rectangular map. The sun illuminates the areas it should at the times we know it does.
Keep in mind this is not a model I can prove. It also seems strange and fantastical...no ends to East and West...do we re-appear on the other side past a certain point? That said, it is no more "fantastical" than the Globe Theory which relies heavily on a faith in so called "Gravity"- the force that supposedly keeps objects down, spins planets, and makes them orbit the sun, with Earth alone in that special place we refer to as the Goldilocks Zone...able to support all kinds of life where other supposed "planets" are barren, too hot or too cold.
I have read the description of Earth in the Book of Enoch, and although it has been a while, from memory this concept is similar or the same. Enoch goes into a lot of detail, including describing several portals that the Sun goes through from East to West, and an Angel that carries it back to begin again once reaching the "end" of the West in the firmament.
Again, I cannot prove this model. The model (this or any other) is not what made me believe in flat earth, and if it were shown to be faulty, I would still know certain things every flat earther knows, such as the closeness of the sun and moon, the properties of water at rest,
how stars/planets really look compared to NASA cartoons, and the fact that airplane trips from E-W, W-E from the same points are around the same length of time, which is impossible if there is a spinning earth beneath them. Just to name a few.
