This is fairly typical of FET.
See, anyone can invent an explanation involving celestial gears, bendy light or invisible unicorns to describe how this could occur on a flat earth. The problem is that it's massively complex in itself and doesn't remain consistent with the myriad of other theories used to explain away the other problems.
However, when you show them a solution to the problem that avoids all these contradictions, is geometrically provable and is incredibly simple and elegant, they'd rather cry conspiracy and go back to wrestling with their flying unicorns.
That's why no argument ever reaches a conclusion on this forum.
Enjoy your stay.
