This is ignoring refraction, a well known effect.You better catch up...
Take a look at a ship on the ocean. As it goes out to sea.. When it goes "over the horizon" get out your telescope and voila... there it is...
There are also many lighthouses, mountain ranges and land formations that are visible from the shore.. when.... using calculations that are attched to the globe... these sights should be well below the curve and far from being visible.
If you ignore refraction, then by seeing 'too far', the earth would still be round, not flat. Just a bit larger.
The light in a lighthouse is at the top, and usually the lighthouse is a tall building. If there are cliffs, the lighthouse is usually on top of the cliffs. If the earth was flat, then there be no point going to all this effort to get the light high up. There would be no benefit.
