I think all this circle/sphere discussion is very much off-topic. Let us drop that line, in this topic.
That said, I must make one minnemooseus comment.

3. Humans were able to observe that different parts of the moon were visible in different positions so as to know it was a sphere.
The same side of the moon always faces the earth.
Oddly enough, this discussion is happening on a day/night that a lunar eclipse happened.
