Legend says that they are footprints of the gods, others believe that they are UFO landing sights, and scientists have their own theories, but the truth is that no one really knows how the fairy circles dotting the Namib coastal desert came to be.rnFairy circles are uniformly distributed round gaps in arid grassland across the Namib which look like polka dots(圆点花样) on fabric when see from the air. The fairy circles of Namibia remain the most famous and fascinating to the scientists who have studied them since the 1970's. Theories about their formation and purpose abounds(有许多), but so far no one has been able to prove beyond a shadow of a doubt that theirs is the true answer to this decades-old mystery.
