There is no way you could tell the difference between old and "newer" lines by looking at satellite imagery. To properly test any theory regarding
the purpose of the Nazca lines you need to have some understanding of how the site has been occupied during certain eras of its existence. Again, you
would need access to data, which has been collected during numerous archaeological survey's of the site, that allows you to layer the lines based on
when they were drawn. A huge problem with the approach of tracing every line, is that many of the things you may trace are superfluous either because
they are irrelevant to the theory you are seeking to test, or are not even true Nasca lines. Due to the aesthetic, subjective nature of the approach,
many of the lines that will end up being traced may not actually be Nasca lines at all. Some may be natural features, others will be lines which have
been skewed by natural occurrences, others still may be modern day paths created by tourists, and a great majority of the lines will be from
significantly different era's of occupation which are not necessarily linked by one in situ non changing culture. To illustrate how much more
complex of a problem this is than many may appreciate, modern professional survey's go to great lengths to reference survey's conducted in the 60's
because the terrain has changed so much over the past 50 years.
To approach this problem properly some preliminary facts should be understood as well. The site has been occupied for 4,000 years (or 2,000 depending
on what journal article you want to follow) but a majority of the lines and petroglyphs date to 400-650 AD. There is a pretty concrete time line of
people moving to and fro Nasca. Changes in material culture at the site demonstrate that the site went through at least five distinct "era's". It is
clear that how people have utilized the site has changed greatly over its period of occupation, and these things are well traced through the
archaeological record (read the articles I posted above and reach your own conclusions).
What is the thesis that you are trying to test?
1) Over the course of a 4,000 year history a distinct, ancient and misunderstood society has been creating some message by means of monumental
construction? The problem with this theory is that most of the lines, if not all of them, date to only 400 AD. Further, we have a pretty good
understanding that the site was not settled during its entire occupation, by one distinct social group. If very ancient lines exist, and some modern
evidence suggests that they may, these lines were likely created by very a very different cultural entity than the people who made a great majority of
the lines post 400 AD. To put this in prospective, think about how much your home community has changed over the past 20 years, than extrapolate that
over millenea. The people who occupied the site 4,000 years ago likely had a very different cultural identity than the people who occupied it 400
years ago. Therefore to get a good idea of what really happens you would have to trace out the lines based on era of occupation, and then if
necessary overlay them to get the most concrete understanding of what was going on at Nasca. Just for note, analysis of material culture seems to
demonstrate an ebb and flow of occupation directly linked to rain and drought activity
2) Did a single event transpire at the site, that inspired its occupants, whomever they be, to transfer a message by means of monumental construction?
To answer this question you would need to know the dates of the lines to properly test it. It is clear that some societal change took place around
400 AD because the in situ culture began making the lines in monumental fashion. What caused this cultural shift is still hotly debated. If you
think that Aliens touched down at Nasca in 400 AD and left behind a blue print, that's a fair theory. But to properly test it you need to know what
lines appeared in 400 AD and what lines appeared prior to and hundreds of years after. Current accepted theories behind the lines appearing in 400 AD
range from textile manufacturing to ceremonial marching. Most people who have studied the culture during this era have advanced numerous arguments
that whatever the ceremonial activity may have been, it was likely related to rain/drought.
Extensive modeling, field testing, and peer reviewed scholarship has been done on this subject, you may want to take 20 min's of your time reading a
couple articles before spending hours on MS paint if you're really interested. If someone could get the data of the actual survey's (i've tried) we
could all actually put some real work into this mystery.
