Yea since I’ve been around the simple construction of rectangular buildings I know the amount of effort and manpower it takes simply to do the foundation of a rectangular building. Let alone put up the walls and roofing. And overall the transportation of all the materials. Just one takes a lot of effort and time. So it makes no logical sense that they were building these type of structures ALL AROUND THE WORLD with simple horse and buggy/ hammer and chisel like technology. Either they were master builders and their knowledge was lost in between the 1800s and now OR they had technology that was lost between now and then.
What is most likely is that these things were already here when cacs took over and they simply repurposed them to their likely while destroying that which they did not want
Nope not buying a “change in style” that “coincidentally” happened when more eyes and cameras/video came around.
You just posting pics but if these are as recent as you say they are, where are the pics/video of the construction process?
