The model currently accepted (why, we are still wondering) by FES can be proved to be wrong quite easily, if we just take into account the orbits of the Sun/Moon/Planets, above the flat earth.
That the earth is flat is very easy to show, the supporting theory is what makes the whole thing a joke in the eyes of the round earth proponents; once the correct model is accepted, there is no limit to what could be done...
Let us take as an example the western shoreline of Lake Ontario:
Here, once and for all, the extraordinary proof that there is no curvature at the surface of the Earth.
Mississauga - Toronto 26.4 km, curvature of 13.6 meters
Port Credit - Toronto 14.4 km, curvature of 4 meters
Some photos are taken from a distance of over 20 km, but, for the sake of our discussion, we will assume all photographs were taken from the 14.4 km distance.
Then, on a round earth, we should see: AN ASCENDING SLOPE, A MIDPOINT VISUAL OBSTACLE OF 4 METERS, AND NOTHING UNDER 6 METERS FROM THE OTHER SHORE.
ALL PHOTOGRAPHS WERE TAKEN FROM THE BEACH.
Here now is the ultimate proof that the Earth is Flat:

Hamilton - Toronto 65.5 km, curvature of 84 meters

(even if we take a distance of 53 km (just as from Grimsby), it would be impossible to see the other shore, from the beach in Hamilton...)

River Forty Mile Creek
Class Ramp
Size Medium
Height: 45
Crest: 20
The Niagara Peninsula Conservation Authority acquired Beamer Memorial Conservation Area in 1964, to protect and preserve the Niagara Escarpment and the Forty-Mile Creek valley system. The site is home to a variety of Carolinian plants and wildlife.
One of the best proofs that there is no curvature over lake Ontario; from 45 meters, we need another 10 meters just to reach the top of the curvature, right in front of you, and then miss the bottom 65 meters of the buildings in Toronto (the visual obstacle). But there is no curvature, no midpoint 55 meter obstacle, the Toronto downtown buildings visible top to bottom. Of course, if you still do not believe it, you are free to go there and see it for yourself.
Here is Beamer Falls:
