Been thinking about this for a while actually. The sheer scale of them only makes sense from the air, right? You can't appreciate the shapes from ground level, so who were they made for? The "landing strip" theory gets dismissed pretty quickly by mainstream archaeology but I always thought that was a bit hasty.
What gets me is the trapezoid shapes specifically. Long flat cleared areas, wider at one end. If you were designing a visual approach guide from scratch you'd probably end up with something similar. Could be coincidence, could be ritual, but it's worth asking the question properly rather than just defaulting to "religious ceremonial use" as a catch-all explanation.
Has anyone here looked into the soil composition research? There's work suggesting the lines were created in a way that preserved them almost unnaturally well. Whether that means anything or not I genuinely don't know.
What's everyones take on who the intended audience actually was? Ground level humans, or something else?
