Look from high above the Earth, and it’s obviously not a ball Earth.
Your curved surface blocks out everything past three miles out from us, curving downward.
When we’ve never seen or understood or known what it would look like above a ball Earth, and told that Earth is a ball, many people think this is how a ball Earth looks from above it….
If anyone who believed this is what a ball Earth looks like from above it, they’d soon understand it cannot be a ball in any way at all.
Just one thing that makes it completely impossible to be a ball, is realized and understood by anyone who has ever seen the Earth from high above it, over a long span of its surface, its blatantly obvious to see its flat, no ball at all.
Horizons could never be seen directly across us, from high above a ball Earth, over two hundred miles away from our viewpoint.
You say we’d always see over the surface of Earth for thousands of miles on it, if it were flat!
No, it’s easily proven a flat surface has no infinite view outward over the surface.
A ball Earth seen from high above the surface, if we ever did see such a thing, would be quite a shock to see, such a vast difference to our view of the flat Earth we see now!
