I don't know. Never claimed to know, and I don't think "flat earth theory" is the end all of celestial movements. There is still a lot of explanation needed for anyone to take it seriously. Either way, that doesn't fix the holes I see in the heliocentric theory. I can only hope to ever know for sure, beyond a reasonable doubt, the shape of the world we live on.
I have yet to see much, if any thing, to take seriously about flat earth. "Flat Earth Maps" ,or the lack of "Flat Earth Maps" , for a start.
It may come as a complete surprise to the so-called "flat earth believers" ,but that 99.9999nth part of the world knows for sure,, beyond a reasonable doubt, that the shape of the world is the globe on which we live.
The difference between "round earthers" and "flat earthers" seems to be that "round earthers" are not afraid when they are uncertain of something, to look up things,or find out how to look up things, but "looking up things" is something "flat earthers" never do because their minds are made up and they are certain the earth is flat simply because if they look out their windows the earth looks flat. That is about as far as they go. Oh, yes ! They must look up things written in 1850 as the source of all truth.
If you don't take flat earth seriously , it can be fun and entertaining. My guess is that is why at least some persons enjoy this website.
