@meymeyshops. That is detailed explanation on your post. It is educative and informative.
The way you presented it is absolutely convincing.
Especially those old believes of Babylonians, Egyptians and Monks

The Babylonians thought that it's in hollow form so as to give space for people of the underworld. Egyptian belief was that it has four corners so it's flat with each corner having a mountain as a support. Even some monks among the early Christendom were said to have supported such flat earth notion and propagated it.

Thank you for explaining to us what was written some years ago at the books of Job and Isaiah. Best wishes
