109) “There are no fixed “East” or “West” points just as there is no fixed “South.” The North central Pole is the only proven fixed point on our flat Earth, with South being all straight lines outwards from the pole, East and West being concentric circles at constant right angles 90 degrees from the pole. A westerly circumnavigation of Earth is thus going around with Polaris continually on your right, while an easterly circumnavigation is going around with Polaris always at your left.”

Incomprehension of geometry

It just doesn't work. Circumnavigating earth at the equator you see Polaris due north and exactly at 0° altitude (horizon-level), whereas at the North Pole it is at exactly 90° overhead. And every other star that you have to take into account during that circumnavigation absolutely makes no sense on a flat earth. Everybody circumnavigating the earth at the equator finds Sigma Octantis at 0° due south, and everybody doing it on the tropic of Capricorn sees it at 23.5°, due south and at the same time.
And now, factoring in the star's rotation, it becomes an even bigger mess because on a flat earth you would get opposing directions being cut off at the equator. This is just wrong on so many levels..

Look at the video in #102.

There is just NO WAY to explain this other than on a globe. I already posted a 100$-challenge on youtube asking for a flat map of earth that can solve this problem. I didn't get an answer because I don't think there is a solution.
