You’re making unsubstantiated claims. That is not proof of anything by any understanding of the word proof. If the earth was flat the sky and sea wouldn’t magically join together at the point of the horizon. If the earth was flat I would be able to the east coast of America from the west coast of Ireland. But I can’t even see Wales from the east coast of Ireland. I can’t see Wales because Wales is beyond the horizon. Well seasons occur, we know that. Can you explain why they occur at different times in different places using your flat earth model? Yes, it tells me we are caught in an orbit within our solar system but also within our galaxy. The vast majority of the stars I see are also in that same galaxy. But when I go to Australia all of the stars change. That wouldn’t occur if both Ireland and Australia were just in different parts of the same flat plane.
