please see a doctor about your inability to keep a thread of thought together. at no point did i ever say when people believed the world was flat, only that they did believe it at one point. your link specifically states that they did believe that at one point in the evolution of human understanding. therefore your link supports my position. Your position that it was only a urban myth that people believed that is not supported.

the more man learns, the more he realises, he really does not know anything.
