Flat Earth Logic

Bring those proof please...

OK, how about two simple ones you can verify for yourself.
- No matter how clear of a day it is, you can never stand on the ground and see Cuba from Key West or vice-versa. No point of land on either island is high enough to see over the curvature of the horizon to the other. Distant mountain peaks are visible at that distance.
- When people in Australia and other southern latitudes look up in to the night sky, it revolves around a completely different point than what people see from any northern latitude. No flat Earth model can reconcile this simple observation. The Moon also appears upside down in the sky comparatively.
*There's plenty more proofs where that came from. Some of them require math, some require special equipment, but some proofs are easy enough to do from home. ;-)

But i can see chicago over lake michigan... who should be under 600 ft of curvature... why does the us navy patented a rail gun for their ship and proudly say with a 100 nautical miles straight and level lining effective range will give em victory? To hit ennemy hidden behind 5500 ft of curvature? This make no sense.... all of the nasa measurement of earth are false

You can see the tops of buildings in Chicago over lake Michigan on a clear day but not the bottoms, and ever heard of ballistics? Yes, you can actually fire a ballistic (non-guided) projectile over the horizon. It all makes sense.
