The landing marker theory is basically dead imo, at least in the "ancient aliens built a runway" sense. The lines are too narrow and the ground too soft to support anything taking off or landing, even small craft. that gets glossed over a lot.
What I do find genuinely interesting though is the water/ritual procession angle that's come up in recent research. The lines following underground aquifer paths makes way more sense for a desert culture obsessed with survival. You walk the lines as a ritual, you're literally tracing where the water is beneath you. That's not boring, thats actually kind of profound.
The alien stuff sells books and gets clicks but it also kind of insults the Nazca people by implying they needed outside help to do something clever. Anyone else been down the geoglyph rabbit hole lately or is it just me on here?
