Bodies of water all have one thing in common, and there is NO exception. ALL BODIES OF WATER LAY FLAT. WATER DOES NOT CURVE. WATER ALWAYS FINDS ITS LEVEL. The earth is simply a group of islands in the midst of a world pond (ocean) which must follow the laws of physics, i.e. WATER ALWAYS LIES FLAT AND IS CONTAINED BY THE LAND WHICH IS HIGHER THAN THE WATER LEVEL.
