You do understand that can't really be answered. We know that the earth was considered a sphere over 2500 years ago, but how much longer before that is unknown.
That's a pretty weak starting OP unless you can flesh it out a little more as to just what it is you're looking for.
Yes I was not sure how best to phrase it.
We can for instance find those who think the Sumerians thought the earth was a disc floating on water and also those who thought they understood the earth was round.
Wondering if anyone has any insight.
