And you should not be convinced.

This data goes smack against everything you have been told your whole life.

Sooo... does light bend over the earth's surface, or is the earth a different shape than what we are told?

The other big clue, that EVERYONE notices, but few think about is that the horizon is always at eye level.

If we lived on a ball, if you got in a plane, the earth should be down. The higher you go, the more down the earth is. But, its not.

Another piece of this is, you cannot see the earths curve from a plane.
Mathematically, given a point on/above a sphere, the area that you can see is a defined as a circle. And that circles is all the same elevation from that point.
So, the curve of the earth you see in a plane is an optical illusion. (because your eyes, being circular lenses, makes circles out of everything)
