Have no FE believers traveled on aeroplanes?
I have been to Beijing severl times, and at 30,000 Km the curvature of the earth is observable to the naked eye through the plexi-glass window. Also, during the flight, after a while, Brisbane (my home city) went under this curved horizon, thus proving that a rounded surface is being tavelled over by the plane. Also add the effects of the tropics, and the fact that Suoth Africa, Antartica, South America and Australia are only a few thousand kilometers apart, as the many tens of thousands that they would be if the Earth where flat. We ad that several air, sea, land (almost) and space craft have gone around the Earth in many different directions using many different courses, and have all arrived where they started without falling off anything.
The ancient Egyptions, Chinese, Koreans, Zimbabweans, and many others proved the Earths roundness before the Christian, and in the case of the first two, Jewish Bibles where written.
I suggest you all use your money to go see if the Pacific is flat, because I've seen that it certainly is not.
