It’s still possible that the flat earth is slightly curved. But even without that assumption, Mount Everest is obviously blocked by many other hills. The sun setting can also be a result of the sun getting farther from us. Globetards like you also can’t seem to explain why the moon glows, nor the fact that the moon and the sun appear to be the same exact sizes. However, the Bible manages to explain this “coincidence”.
GENESIS 1:16 - “And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: He made the stars, also.”
What it means by greater and lesser is that the sun’s light is stronger, so it has nothing to do with size, and they’re both lights. This explains moonlight, which NASA can’t seem to explain. Furthermore, the stars are referred to separately from the sun, proving that the sun is not a star.
