Another explanation is that the lines may have been made for religious reasons. British researcher Tony Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by the side of the road. It’s possible that in the past, the lines of Nazca were created for a similar purpose.          (49) But the local people have never constructed anything this big.

Recently, two other scientists, David Johnson and Steve Mabee, have speculated that lines could have been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every year. While Johnson was searching for ancient water sources in the area, he noticed that some waterways built ancient people were connected with the lines. Johnson believes that the Nazca lines are a giant map of the underground water in the area.       (50)

A. Other scientists are now searching for evidence to prove this.

B. A Swiss writer named Erich Von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.

C. Scholars differ in interpreting the purpose of the designs.

D. The largest pictures may have been the sites for special ceremonies.

E. Seen from the ground, it looks like lines scratched into the earth.

F. He called Nazca “the largest astronomy book in the world”.
