      Flat Earthers hummmm, We’ve known the earth if not flat for thousands of years. I think the easiest one is tell them to watch a ship sail over the horizon, it’ll look like it has sunk if you assume the world is flat; but it hasn’t sunk, it’s gone round the globe a bit.
      It works with tall buildings too. This link shows the Chicargo skyline with photos taken from different distances sailing across Lake Michigan.
