1. Notes from my research
1. Pictures from astronauts prove that it is a sphere. It could not spin if it was flat. People traveled by boat all around the earth 360 degrees and ended up in the same place they started. You would see many more thing ahead but since it is round you only see a couple things ahead that are close since they are point above the thing you where looming at. Pythagorus was the first to figure out the earth was round. The moon you could see it's round from the quarters and full moon also the half moon. The earth must be a sphere because of the end of the arc/rounded shadow on the moon during an lunar eclipse. Ships appear to sink as they pass over the curved surface of the Earth. The pull of gravity is about equal from any point on the earth's surface.
2. Notes from videos
2. The time zones would not change if it was flat. The sun and/or the moon would never change altitude.
