Earthworks in Kazakhstan

Those who read this blog regularly know I am, by no means, a scientist. But it seems to me that a truly major discovery has been made. Scientists are calling it an earthworks, the largest ever seen. These earthworks, which were found in Kazakhstan, are geometric figures of squares, crosses, lines and rings the size of several football fields; they can only be seen from the sky. Thus far, 260 earthworks have been discovered; they are mounds, trenches and ramparts — arrayed in five basic shapes. 

The fellow who discovered them thinks they were built as “horizontal observatories to track the movements of the rising sun.” The question is how sophisticated the works are; maybe we need to rethink some of our ideas as to when civilization began.
