On eratothenes observation and explanation:
I can take a flashlight and hover it over two salt shakers on a table. The shadow angles produced by the flashlight on the table can give me the same result to what eratosthenes observed in his shadow experiment. Now is the table flat or a ball? And does this suggest that the sun is a local light source and not a supposed big gas ball millions of miles away?
