"The sun and moon, each 32 miles in diameter, rotate at a height of 3,000 miles above sea level. As they are spotlights, they only illuminate certain places. This explains why there are nights and days on Earth. The stars are at a height of 3,100 miles above sea level, which is as far as from San Francisco to Boston. In the dark energy model, the celestial bodies are spherical and are made of ordinary matter. These spheres are being held above the Earth by DE."
These claims, while refusing to accept other scientific evidence, are the major downfall to your theory. Although I praise skepticism, your assertions of certain facts about the FET contradict your use of the Zetetic method. Is is useless to debate scientific facts or observations, as any evidence can be refuted or considered part of the conspiracy. So why should the claims of Flat Earthers be trusted over any other claims? The only logical skeptical position would be to say there is no absolute certainty whether the earth is round or flat. Under the Zetetic method, to claim otherwise would be to say that you have measured the earth yourself, measured the distance to the sun and moon, directly observed the ice wall surrounding earth, and created your own maps based on exploring the earth yourself, not trusting any observations made by other Flat Earthers or anyone else. Why trust Rowbotham's assumptions over any other scientist? This confirmation bias, which is incredibly intellectually dishonest, is a direct contradiction to the skepticism you use to refute the RET. How can any of your theories' claims be held true, if you apply the same skepticism to your own claims?
