The Mysterious Lines and Shapes

I've been searching for the long 40 for the answer to theres confusing shapes and lines. I now beieive I understand the answer to them. They were formed by the Nazca. These lines and figures were scraped into the sand with shovel-like objects. Then incredibly straight lines and curves were created by placing poles into the ground and then scraping away the rocks and dirt to reveal the light colored sand underneath. But why were the lines and shapes here? The lines are pathways for the Gods. They believed if you followed theres paths, you wojld eventually come to the Gods, so they continued to make them as far as they could, but never found the gods, and so started a new path.
