@TheWatcher – Yes, there was a German woman who dedicated her life to studying the Nazca lines – Maria Reiche worked at first with Paul Kosok, and spent many years elaborating on her mentor’s theory that the lines were constructed by the Nazca people to serve as a giant calendar. She worked on the idea that the lines expressed astronomical observations made by the Nazca people (note: the Inca were also quite aware of astronomy, as were the Maya and the Aztecs).
Reiche never claimed the lines were made by anyone except the Nazca people.
The folks who claimed the lines were made by aliens included James W. Moseley, Louis Pauwels and Jacques Bergier, and of course, Erich von Daniken. None of these people were women, and none of these people have any support from anthropologists, archaeologists, or astronomers.
One other person, G. von Breunig, thinks the lines were made by folks running footraces and following specific patterns that may have had religious significance.
The main reason that some people keep insisting that the lines were constructed by aliens is that they cannot leave behind their Eurocentric viewpoint that civilizations outside of Europe were all “too primitive” to have been able to do something like the lines. It is a form of racism.
