Spherical,
I am new to this flat earth concept. I checked out the link you list but it wasn't very helpful. Are you denying the validity of logic and science, or are you saying that there is scientific evidence that is being withheld?
Firstly, I have seen a number of videos where a camera was attached to a balloon and sent up above 90,000 feet. The balloon bursts and the camera parachutes back to earth. A search on youtube for "high altitude balloon" turned up over 55,000 videos. One can clearly see the curvature of the earth in these videos.
Respectfully, how do you explain this phenomenon?
A second question I have about your belief is why do airliners take the "great circle" route when traveling long distances. They would not do that if the earth were flat.
Also, one can actually determine the size of the earth's sphere by measuring the angle of a stick at noon at two different latitudes. This is one of many ways the ancients knew the earth was a sphere 2,000 years ago. They even created a "computer" now called the Antikythera device that used this calculation and was then able to calculate the earth's relationship to the moon and planets.

Lastly, the trade winds are a direct result of the earth's rotation. That must also be explained if the world is flat.
These are sincere questions and I am giving you the benefit of the doubt at the moment. Are you able to explain these phenomena according to a flat earth cosmology?
Thank you.
