i think the ancients saw the world as round. i believe these diagrams to be a perfect description of their beliefs. they knew of an atmospheric curvature of (the cosmos,sky, the above), the cosmic & sky deities, & (the middle earth) earth deities, (earth & water) & the round under-earth known as the underworld, (fire) many underworld gods & goddesses were transformation god/desses, just as lava from a volcano transforms the formation of earth. all of the most ancient deities are simply how the ancients described science & biology, the deities & mythos were simply stories passed down about how the earth was created , how it works & how its all connected in cyclic fashion.
i haven’t personally explored space, so i don’t have personal evidence to be on either side of the debate from a periscopic astronomical view point. i engage both sides of this topic without “my own” conclusive factual evidence. i don’t base my “ultimate” 100% answers on beliefs. i need to see, to believe if we are talking about such an objective scientific truth such as this. though there is enough evidence & science that makes me 90% sure that the earth is indeed round. it would be amazing if nasa took flat earth conspirators on a space mission & filmed the whole thing, for all of us to witness. it would be the best reality t. v. series ever in my opinion. it would be like the Truman show in space, & probably the most watched series.
