Nazca Lines, Overpopulation, Death Penalty,Gods of Earth

Once again it is about the “scrape pictures” at Nazca in Peru. On the 16th March 1987, at the 216th contact, you explained that it has been a gigantic religious and astronomical calendar and garden. I explained this information to somebody, and of course new questions resulted therefrom, and I am also interested in the answers. Can you give me additional information about those scrape pictures, their purpose and construction as well as about the Nazca gods and Nazca people?
