Fortunately one thing that most scientists can agree upon is how the lines were made. At first the enormity and preciseness of the lines seems to point to a remarkable feat of engineering. Many of the drawings must also be viewed arially to see them in their entirety, and thus it was thought that it would have required an airborn observer to aid the artists in creating the precise figures and proportions we see today. However, according to Dr. Persis B. Clarkson, an archaeologist and geoglyph expert at the University of Winnipeg “ It was not a difficult technology.all you need is the will.” It would have just taken careful and diligent attention to sight the lines. To prove this, a group of 10 Earthwatch volunteers helped an astronomer and anthropologist, Anthony Aveni, in a study of the Nazca lines. In just and hour and a half, without a printed plan, they created a straight line winding into a spiral 35 meters long and one meter wide. Splitting into groups, each one performed a different task, and the result was, according to Aveni, a figure as accurate as any Nazca drawing measured with a surveyor’s instrument. It is fairly conclusive that it was not necessary for the Nazca to have possessed great mathematical or engineering skills to create the figures or lines in the desert. It was possible simply by people working together with their eyes and hands. So there is one of the mysteries cleared up.
