If its flat:
1. How is it that the earth makes a spherical shadow on the moon on a lunar eclipse?2. How is it that you cannot see Mt Everest from a telescope from anywhere on earth?3. How is it that we cannot see Japan or even Hawaii form any telescope from California? 4. How is it that some places are light/dark for 24+ hours to months?5. How is it that the sun sets below the horizon every night?6. Why does a hurricane deflect to the right on the north side of the equator and on the south side of the equator they deflect to the left?7. The stars at night change depending on where you are at. Orion is upside down if you are in Australia, how can that be possible on a flatearth?
