You travel south far enough and you stop being able to see certain stars, and start seeing others, that also appear to rotate around a central point. This is easy to explain with a spherical Earth; how would you explain it if the earth is flat.
Then there is the ISS, which even with an amateur telescope you can clearly tell is an artificial object, moving quickly across the sky. I have seen it personally. My father, who got me into stargazing, remembers it not being there, and beong excited to see it go up. How do you explain that?
