Notice that the first video already shows the earth as a ball, the gopro camera (wide angle lens) is what causes this. These are the types of cameras that are used by nasa. If you could picture a flat round dinner table, sizing yourself down to replicate the table being earth, than as you lift up in elevation the edges of the table are round, so there will be a curve, yet the surface of the table is flat. This is just one example of a flat earth model. And to me shows that there could be numerous models with reasonable accuracy, and yet still be wrong. With a flat earth model, numerous kingdoms/nations/civilizations was able to predict eclipses, hold feasts and ceremonies for them, and also navigate. All while without even knowing of the different cultures, and yet agreeing on a flat earth. It takes persuasion for one to believe otherwise.
