Let's look at the markings more closely. The lines are quite different from modern vehicle lines, also seen increasingly at the site. A four-wheeled vehicle has the width of the twin tracks fixed because the wheels are set apart on fixed axles. Turning is easy because the front wheels turn together. In earlier centuries, cart or wagon tracks had animal hoof marks down the centre. There is nothing like that at Nazca. A modern two wheeled bicycle or motorcycle leaves a single track, but it is wavy as the front wheel is moveable. The lines at Nazca are so straight that in a MILE there is less than 12 feet in deviation. The Nazca lines sometimes make a hairpin turn or a zigzag but never a wavy line. Each line is said to end at a delineated surface; another line, a design, or another star-like centre of radiating lines. Some end at a cliff edge or rising up a hill or mountain side. A line crossed any difficult terrain in its way, without deviating.
We note that these single continuous lines are perfectly straight except where they form part of a design. The Nazca lines are irregularly spaced and often cross over one another. There is no vegetation or building construction there, so the purpose was not to set boundaries. The very nature of the lines shows us they were not likely to have been created by toiling peasants worshipping some god or goddess. The lines were not paths because they go nowhere that's been inhabited. The fact that lines cross over one another, in a way that shows us a line crosses over a line previously there and has a different length, indicates that there was some function involved when the lines were made.
The extreme straightness of the lines implies speed. The only means we have of moving at suitable speeds to require or create anything like such straight lines as these are our trains, and aircraft moving on the ground when landing or taking off. When a jet aircraft crosses a clear sky at 33,000 feet it leaves a trail in a straight line. The function of the plane is not to produce a vapour trail. The function of the plane is to move people and goods from one place to another as quickly, directly, and cost-efficiently as we know how. In the process of performing that function a temporary vapour trail is left in the sky. I'm suggesting that in the same way whatever the function was involving the Nazca plain, the straight lines are a by-product of that function and not the purpose of the function.
Where are the longest straight lines produced in our civilization? The answer seems to be electric power lines, superhighways, railways and airfields. The common factors are transmission of utilities, goods and people. But there is no evidence at Nazca for transmission of utilities as we know it. We are left with transportation of goods and people. That agrees with the remarkable congestion of lines in certain areas, which suggest traffic:
(Henri Stierlin, Nazca La Clé du Mystère: Éditions Albin Michel S.A., 1983, Paris, provides this representation of the remarkable main Nazca site)
The only related type of earth-bound function that seems to me at all comparable is a large railroad marshaling yard. There the function is to disconnect freight cars from arrival trains and shunt them around for re-connection with related destination trains. These yards were favourite air bombing targets in 20
century wars. They have a series of twin tracks, and the incoming and outgoing lines can be traced to population or industrial centres. At Nazca most of the outgoing ?incoming? lines can be traced to a cliff edge, so earth-bound travel to destinations cannot be established here. A closer match seems to be this, a US aircraft carrier:
Here we have a trapezoidal platform with its borders clearly marked plus a central line as well as another platform with broken lines along the sides for guidance. This is closer, I suggest, to the Nazca lines because at least we have trapezoidal shapes and lines that end abruptly, although not at a cliff face, but at the edge of a strip overhanging water. Yet this is very small in comparison with Nazca, where the area we have shown is about 3 miles x 1.7 miles.
