To the person above who noted this, yes, it is entirely possible that the Earth is cylindrical with the bottom rocky section jutting out. Sorry, if I missed any question. If I did, please just point them out like Scott but please also make sure that you're not asking a question I already answered. The sun and moon circle the Earth at a height of 3000 miles at its equator , located midway between the North Pole and the ice wall (which is why that area is the warmest part of the planet and further away it gets colder). Each functions similar to a "spotlight," with the sun radiating "hot light," and the moon "cold light" for lack of a better term. As they are spotlights, they only give light out over a certain are which explains why some parts of the Earth are dark when others are light. Their apparent rising and setting are caused by optical illusions. Depending on the time of year and where you are located, these spotlights will be in different areas. This is basically the same theory that exists in mainstream science though where it's the Earth moving and rotating in there, it's the sun and moon that do so in reality.
