Floundering? Please.
Replying with over exaggerated models and resorting to the "you're an alt" accusation. Yep, that's floundering.
More evidence has been presented in support of Flat Earth than anything Round Earthers have EVER dreamed up.
--Polaris (North Star) never, ever, moving from its place in our sky.
--All the constellations staying exactly the same throughout all of recorded history despite the four 'alleged' and unfathomable movements of the Earth through space.
--The '50 mile long' Panama canal that is officially 'perfectly level' from end to end.
--The Bedford Level experiments.
--Countless photos and videos of horizons many miles long with zero curve.
--Crepuscular Rays indicating the close proximity and small size of the sun-disproving much of the myths about space and our solar system, etc.
--Mercury and Venus being visible in our night sky when they're 'supposedly' closer to the sun than Earth making it impossible for them to be seen when the Earth is turned 'AWAY' from the sun (i.e. night time).
The list goes on and on.
Polaris is really far away. Learn how scale works.
The constellation do change over time. Who said they didn't?
The Panama canal uses a series of locks to raise ships to the higher elevations of the lakes along its course, but each body of water is 'level' from one end to the other. That's how it works on a globe.
Bedford Level.... classic example of refraction courtesy of cooler air just above the water.
With each point of the horizon an equal distance from the camera, and not being very far from the surface, left to right curvature will not be very apparent.
Crepuscular rays also indicate a very small sun right in the tops of the trees from what I've photographed in the past. Or, maybe you should learn how perspective works.
Mercury can be visible about an hour before sunrise and an hour after sunset, and Venus visible much longer before sunrise and after sunset. Try looking at a scale diagram of the orbits of the inner planets and draw some lines from the orbit of Venus and see just where it can intersect Earth.
Sure, the list goes on and on with all sorts of stuff flat Earthers don't understand.
