And to add insult to injury, how about a small dose of Erich von Däniken?

The Nazca lines are communal. Their creation took hundreds of years
and required a large number of people working on the project. Their
size and their purpose have led some to speculate that visitors from
another planet either created or directed the project. Erich von Däniken
thinks that the Nazca lines formed an airfield for alien spacecraft*, an
idea first proposed by James W. Moseley in the October 1955 issue of
Fate and made popular in the early sixties by Louis Pauwels and
Jacques Bergier in The Morning of the Magicians. If Nazca was an
alien airfield, it must have been a very confusing airfield, consisting as it
does of giant lizards, spiders, monkeys, llamas, dogs, hummingbirds,
etc., not to mention the zigzagging and crisscrossing lines and geometric
designs. It was very considerate of the aliens to depict plants and
animals of interest to the locals, even though it must have meant that
navigation would be more difficult than a straight runway or a large
clearing. Also, the airport must have been a very busy place, needing
37 miles of runway to handle all the traffic. However, it is unlikely
spacecraft could have landed in the area without disturing some of the
artwork or the soil. There is no evidence of such disturbance.
