The scale model of the formation makes me feel confident that it's a natural formation. It just doesn't look like something people would design, nor even a quarry that makes any logical sense.
I've found a video on Youtube... and I have to agree. There's very odd shapes for sure, but nothing that can be absolutely considered man made.
This article really works to present the manmade view as dominate, which doesn’t seem to be the case at all. Seems like a fun site to read and imagine though.
Not every design make sense.
I have lived on the internet long enough.
