While I was in High School, my Geography teacher taught us about the sphericity of the earth (it's roundness). She gave us lots of evidences to support her claim. Out of the reasons she gave, I can only remember two right now. That was about ten years ago.

1. If the Earth 🌎 was flat, people/ships/animals would have fallen off the edge by now. This evidence was credited to a group of sailors who sailed ⛵ round the world without seeing anything like an edge.

2. The alternating day and night. The fact that we have day and night is as a result of the rotation of the earth (and its only round objects that rotates). The part that receives light from the sun has day while the other experiences night.

Forgive me if I'm wrong, but it's something I learnt a long time ago.
