The diameter of spots varies from two to fifteen meters, and the total number has long been in the thousands. This phenomenon is observed only in the lands far from major population centers, so a large group of enthusiasts that created this myth, and for many years to support it, can not speak.
According to the beliefs of the people Himba, living in Namibia, circles appear because of the fire breathing dragon that lives beneath the earth#39;s crust. Other, more realistic hypothesis put forward by scientists believe that the reason for this phenomenon lies in the activities of ants, or plant or was caused by the influence of toxins and chemical waste.
The most convincing explanation by the German professor of biology Norbert Jürgens (Norbert Juergen), which asserts that the appearance of stains caused by a complex activity sand termites. According to him, these insects are eaten all the vegetation within a small circle and buried in the ground. The lack of vegetation allows moisture to seep through the sand, so that even in the most arid conditions underground termites maintained a small reserve of water. 
Biologist Walter Schinkel (Walter R. Tschinkel) conducted an independent investigation of the origin of the puzzle spots, but no trace of termites in them is not found. Scientists debate about the origin of crop circles Namibia and continuing to the present day, and the unsolved mystery only adds spice to pictures taken in those places.
