the Earth is shaped like a soccer ball, except wider at the Equator than the Poles, due to the Earth's rotation.
Who CARES what Columbus said? Columbus was a fifteenth century navigator and a very good one. He established the Canaries current route to the Western Hemisphere. However, as far as he was concerned the world very well could have been flat, nothing he did took any account of the Earth's Sphericity in any significant way.
What are you trying to say here? Round means round. I don't know how you can twist that? Lol. Columbus didn't have satellites circling the earth now did he? I think I will stick to our modern satellite data.
