Speaking of poles...
if the Earth was flat the north and south pole would both be in the same place - there would be no such thing as a working compass. north would be up and south down, or vice versa.
so the existence of compasses proves the earth isn't flat. literally trillions of fully repeatable magnetic field measurements performed daily for a thousand years are an inescapable proof.
