if earth is not round, then lunar eclipse should show earth shadow edges that are not curved in the same way every time.
if earth is round but flat and not spherical, then lunar eclipse should show a round shadow flattened by perspective unless the moon happen to be directly overhead at the time of eclipse.
we never see either of these in any eclipse despite the fact eclipse can occur at any point along the path of the moon in the sky. the only shape that will always cast essentially the same round shadow on the moon would be a sphere.
I believe people millennia before invention or telescope had already figured that out.
I would come up with a few more reasons but i highly suspect adding any more information to the original poster’s brain necessarily displace some vital autonomous nervous function like breathing from the limited brain space.
