I got to thinking about this (I know- this way lies madness!), and could not for the life of me visualise how such a model could account for the differing lengths of day and night throughout the year.
The answer, according to highly qualified flat earth scientists, is that the sun changes its orbit.
6 times a year.
This is proved by astrology.
Well, that's me convinced.
I only made it through the first 5 minutes of this "mindblowing proof", and I would recommend the same to anyone interested/ brave enough to check it out.
