100% undebunkable proof that the earth is not flat. but read the proof before you ban me please:
if the earth was flat we would be able to see all stars from all sides of the earth. which dosen't happen. also you claim that objects that are far away can't been seen beacause human eye records ~450 Mp but then how do we see the stars that are supposed to be 0.5 from the lenght of the plate away from us. also planes aren't effected of the atmosphere beacause the gravity is stronger. we don't feel the earth's movement beacause we cannot feel speed. we can feel speed changes. take an experiment: use an elevator and close your eyes. no press the button to move the elevator. you can feel that  the elevator moves at first but then you have no idea. u still feel something beacause the elevator dosen't move at 100% stable speeds. give me proof that the earth is flat and i will debunk it for you
