Eratosthenes never questioned or sought to determine the shape of the world in any way. The calculation he used requires the world to be spherical (and many other unvalidated assumptions), otherwise his result is meaningless.
Ancient people knew the earth was spherical because they were taught it was fact from childhood, just like today. It was never validated/measured, they just believed it was true and disingenuously/erroneously taught it as fact to children.
I also agree with the OP; the shape of the world is not a conspiracy, nor is a conspiracy required to be stupid and wrong as humanity always is historically.
