In 1985, the archaeologist Johan Reinhard published archaeological, ethnographic, and historical data demonstrating that worship of mountains and other water sources played a dominant role in Nazca religion and economy from ancient to recent times.
Even though we know exactly how the lines were made, there is less existing evidence concerning why the figures were built, so the Nazca people's motivation remains the lines' most persistent mystery. Many scholars believe that their motivation was religious, making images that only gods in the sky could see clearly.
There are several thousand simple lines and geometric patterns on the Nazca plateau and surrounding regions, as well as over seventy curvilinear animal, insect, and human figures in the Nazca area alone, with more in other areas. The area encompassing the Nazca lines is nearly 500 square kilometers (200 square miles)
Since their discovery, various theories have been proposed regarding the methods and motivations underlying the lines' construction. The archaeological explanation as to who made them and how is widely accepted; namely that the Nazca people made the lines using simple tools and surveying equipment.
