No, completely wrong, everything in science and mathematics points to a spherical earth. There is certainly no reason for such a lie to be formulated in the first place and the whole concept of a flat earth just wouldn't work. for the reasons below. The whole theory makes the earth sound like a giant cheese board - but then I could never believe in religion to such an extent whereas 'a god' designed human life under a cloche.

The earth is flat, not spherical - in the flat earth plane of existence everybody stands upright (unless through ill health, or disability, or when sleeping, laying down, etc), everybody walks the right way up, everyone has the same perception of what is up, and what is down, what is to the right, and what is to the left of them. It rains downward everywhere. Aeroplanes fly the right way up from place to place, and boats well they too sail the right way up, etc, etc, etc, there is no need to accommodate wrong way up standing people in the flat earth module! Aeroplanes and birds don't have to be accommodated flying upside down, or the wrong way up, and in the flat earth module we don't have to accommodate it raining upwards from the sky below!
It's simply all nonsense that the earth is spherical / a globe..
