Did the Nazca people actually live near the lines or were they just used for rituals?

The ritual use angle makes more sense to me honestly - the lines only really "work" as images from altitude which suggests they were never meant to be experienced at ground level by daily foot traffic. If people were living right on top of them that'd be a nightmare for maintenance alone. That said the ceramic evidence found near the plateau suggests settlement activity wasn't totally absent from the region, so maybe it was more of a seasonal pilgrimage situation where communities travelled there for specific ceremonies and then cleared off. Would love to know what the spirit behind that kind of effort looked like from a cultural standpoint. Anyone here looked into the water/irrigation theory? Feels underrated in these discussions.
