I asked you to tell me what force causes a bowling ball and a small rock to fall at the same speed. It cant be density.
Did you ever take a land navigation course in the military? If so then you would know the earth is a globe.
The constellations move. The north star barley moves because it's close to the north pole axis.
You would also have learned that in the southern hemisphere that you cant see the north star and you have to use different stars to navigate.
You would also know the further north you go the higher the north star is in the sky and above about 70 degrees you cant use it for navigation.
Its the same reason you can put a stick in the ground and mark the end if the shadow and in fifteen minutes and mark it again and that gives you east and west line.
The earth is not flat. The sun doesn't vanish. It sets over the horizon. If it was flat it wouldn't go over the horizon. Plus the sun would have to be a spotlight.
All this adds up to a globe.
