The movement of the SUN and MOON on a flat plane.... BUT... I believe today, that we are the ones turning under the lights. The MOON is just a reflection of the GREAT LIGHT from the SUN. I picture the WORLD inside a frozen egg-like blog with crystal hard snow wrapping us from the ETERNAL LIGHT that surrounds it. A small hole opening (the SUN) lets in a tiny beam of it into our frozen blob. This beam melts the solids inside and liquifies it, the cold temps freeze it instantaniously. This action causes a movement. After a long time, the Sun has made a complete cut out circle around us and lets us float freely in the water "ocean"- WE turn like a merry go round. Thus, the LIGHT never moves, but WE do....very slowly everyday and night.
