You could be right but lately I've seen a lot of very good arguments that have got me thinking big time about this subject. Check out Eric Dubay on you tube and Rob Skiba. There are a lot of trolls on you tube that make it sound crazy but these guys have some serious arguments that make sense. You can check out some simple evidence for yourself; try finding curvature. You won't. The formula for curvature given by "science" is 8 inches per mile, squared. That is very steep and could be seen easily if it existed when viewing an ocean horizon. There is a photo of the Chicago skyline from across Lake Michigan at a distance of 60 miles which should not be visible if the earth had curvature. (60 squared times 8 inches = 2400 feet below the horizon)
If you watch an ocean horizon, the distance you can see to the horizon is only half the distance you can see to the left and right of that and yet you don't se any curve. If a ship disappears from view they tell you it went over the curve. If this was true you wouldn't be able to bring it back into view with a pair of binoculars, but you can.
