In that case you would see the Sun becoming dimmer by moving away above you. Clearly we can all observe that it falls below the horizon. Sun setting and rising can only be explained by an Earth shape that is something other than a flat plane, simple as.

dimmer like nightfall which is exactly what happens?

which has been shown that you can zoom in on and bring the sun back with high zoom lenses when it goes over your 'curve' same as with boats etc

the earth is level and not a planet which is the word originally used for wandering luminaries 
which as well arent planes like the earth but sonoluminescense
