Yes we can prove it is a ball its been proven a ball times beyond count from indepdent scientists to ancient scholars from goverment run organizations to youtube channels that dont even get paid from the goverment
Section A:
Seasons
Seasons could not work on a flat earth plane because in models of fe's ive seen the sun rotates around the "Dome" and they horribly mis represent light
Section B:
Boat theory
Basically boat theory is the theory of if a boat goes over the horizon then they disappear from bottom up pretty basic stuff easy to see etc
Section C:
Cameras
Multiple LIVE STREAMING cameras have captured the earths curvature (even though multiple fe sources disagree) and its not fish eye lenses funfact fish eye lensess actually make things less curved at a angle and more curved at others
Section D:
Gravity
How would things fall down (simple question)
since gravity is basically attraction of mass, and our earth is slightly squished from its poles (due to rotation) we know that is the reason for gravity being weaker at northern places
according to quantum physics we can expect there being graviton, (yet it has not been detected but it doesnt mean it's not true, it just means we havent been able to observe it physically)
