sure here ill give you one evidence that disagrees with what your claiming. If the Earth was flat, we would be able to look out and see very far, assuming that there were no buildings in the way. We could see another city thats hundreds of miles away. Or a ship sailing out to sea. The boat would stay in view no matter how far out to sea it went. However, if we look out when standing on the ground, we cant see that far. We cant look out into the distance and see a town thats miles away. And a ship will slowly start to disappear from view as it gets farther away. This is because the Earth is round. Things in the distance are not visible because there is a curve to the landscape.
I'm not talking about the current earth , I'm talking about the people that control us might live in a real flat earth..
