Some background: My SO told me an anecdote about her metaphysics class where her professor asked them how can they proved that the earth is round and the prof stumped every answers to his question even they gave facts (don’t worry, it’s just an ice breaker, it was just for fun as a class introduction). I don’t know any specific details on how the professor replied to the students and I’m just curious how it was possible to prove that the earth is round philosophically, or at least, in the perspective of philosophy.
Another reason I’m curious about this is because I remember watching that Vsauce video about the past where Michael talked about the Last Thursdayism. I have a gut feel that deductive reasoning or philosophical razors have something to do with this.

You can look at the pictures from the moon and can clearly see is round. All the other major planets are round. The only way the sun works with day night cycle and our moon is if it’s round.
But if you are trying to convince a flat earther you will never. Conspiracy theorists can never be convinced. Don’t waste your time.
