The Earth must be curved. So, the simplest model I can make is that the Earth is a sphere.” That is pretty good thinking for happening a long time ago. And maybe Eratosthenes had this thought: “If the Earth is a sphere, perhaps I can measure the distance between Alexandria and Syene and I will know the length of an arc segment of the Earth.
