A few questions:
1. If the Earth is flat, and the Sun is in orbit above the flat Earth, please explain sunrise/sunset, where the Sun follows the ecliptic and rises and sets at the horizon. Seems to me that if the Earth is flat with the sun orbiting above, "sunset" and "sunrise" should show the sun just floating away across the sky.
2. You say the Sun is 32 miles in diameter and orbiting at an approximate altitude of 3,000 miles. Commercial jets fly at 29,000ft and higher. Some military aircraft have even higher service ceilings. Why have they not achieved an altitude higher than that of the Sun? Oooooops. . . I was thinking feet on this one.
3. Qantas flight QF 63 often flies from Sydney, Australia to Johanessburg, South Africa, following a polar route across Antarctica. In a flat Earth model, wouldn't they have effectively flown off the planet, even though they ended up in South Africa, supporting a round Earth?
4. If the Earth is flat, what's keeping satellites from crashing to the Earth? Moreover, what's keeping them in orbit?
5. I own a high-powered telescope that can resolve the rings of Saturn from my porch, a distance of 746 million miles (1.2 billion kilometers). That being said, if I stand at the summit of say, Mount Kilimanjaro in Tanzania, at an altitude of 19,300 feet, why am I not able to look at the Chrysler Building in New York City, a distance of approximately 7,500 miles (12,100 kilometers)?
6. Why do ships sailing away from you disappear over the horizon keel-first, and vice-versa when approaching you?
7. Explain the reason you cannot see Polaris and other northern celestial objects from the southern hemisphere.
8. If the Sun is only 32 miles in diameter, what are the other planets orbiting? They are very clearly following the ecliptic within a few degrees either side.
9. What's on the "underside" of a flat Earth?
10. Why do stars cross the night sky in the same direction that the Sun does? Does that mean that all the stars are rotating above our heads too?
11. If the Earth is not round, rotating on an axial tilt, and traversing an orbit around the Sun lying at the center of our Solar System, explain why we only see certain constellations at certain times of year, e.g. Orion in the winter, Cepheus in the summer etc.
12. Explain gravity.
13. If the Earth is flat, explain our magnetic field.
14. In a flat Earth model, Antarctica is an "ice wall" comprising the outside circumference of the planet. Where then specifically is the geographic South Pole, or
90.0000° S, 0.0000° W? I can't see any way to define it to one singular point, whereas the geographic North Pole sits roughly at center.

15. Explain from this photograph taken from the Moon during the NASA Apollo program the following:
a. Why you are only seeing a portion of the Earth.
b. Why the "Antarctic ice wall" that forms the perimeter of a flat Earth is missing.
c. Why Earth is roughly equally divided in partial sunlight and partial darkness.
d. Why the Sun is not shown orbiting above the Earth?
e. Why the
terminator is curved, supporting a round Earth and not a flat Earth.
f. The sheer distant this photograph portrays, disproving that the Moon is only a few thousand miles above the Earth.
