I personally doubt the official spinning ball in a vacuum theory. Although I try to stay open minded and am always open to change my opinion. The biggest problem with the ball theory I see is the fact that we are able to see hundred plus kilometers away which is geometrically impossible on the official size of the ball earth. You have to believe in magical refraction in order for it to make sense, and I have never seen it experimentally proven in any meaningful manner, even though I did look for it.
