here are some of my questions:
Where does the horizon come from?
Why do things fall down if gravity does not exist?
has any FE tried flying a plane over Antarctica to try and circumnavigate that way?
If we live on a flat earth and it is all there is, where does it come from?
if the stars and other extraterrestrial objects are in the sky, relatively close, what is beyond them?
what is the earth moving through?
what is evidence for the flat earth theory other than the fact it looks flat?
While answering these questions please do not state that water "holds it's own level" because even on a globe earth, due to gravity the water is level relative to the center of mass of the earth. also if you can please do link sources that you have used previously.
sorry for the extra long post but I just wanted to understand FET and some of the reasons behind it.
