Limestone, Granite, Andesite, and Diorite stones weighing hundreds, thousands, and tens of thousand of tons... cut, quarried, fashioned, transported, and assembled!
Monuments built to advanced mathematical understandings. Structures built beyond modern day precision specifications.

Slaves built not a thing

I'm no stone mason, but if I were given the task of building any of these awesome structures, I would have to humbly refuse. Even if I were given the proper training to build such remarkable works, I would still refuse. I'm serious.
Many times while pondering at work, I become completely baffled at how these ancient structures were created. With my mathematical understandings, machine experience, and metal-working skills... I can not even fathom how these sites were made.
I told you guys what I'm capable of doing in the beginning of this thread. These ancient sites were built with even more precision than I can accomplish, with even larger and tougher buildings materials.
Sometimes it is very difficult to get a piece perfect. Sometimes a machinist will face hour upon hour of frustration to reach the required precision measurements. It is very difficult to machine separate parts that I interlock with another part. It is a headache to make something perfectly flat, or perfectly squared, or perfectly round. Sometimes we mess up and manage to save the piece by welding on new material and recutting. You can't weld stone. If we accidentally drop or bump a part, we can polish and fix it. Stone will crack and break...
I can not stress enough that even on the scale that I work with, it is extremely difficult to machine separate parts that fit together so precise that there are no gaps, and all edges are running parallel and true. It is not impossible, however, it takes much skill and is extremely difficult to fashion separate pieces that assemble with complete precision.
Not everyone can be a precision machinist. I have witnessed many people come into this trade and totally flake out. Either they have problems learning and operating the machinery, or they have problems with math, or they have problems reading blueprints or program language, or they do not have the proper feel to measure accurately. Some people just can't make a good or accurate part to save their life!
No way were any of these ancient structures built by forced slave labor! It would have taken advanced education, proper training, prior experience, and most importantly... the workers must have taken great pride in their work. If they do not pride themselves as craftsmen, the precision will be lacking. Trust me, it is honestly a labor of love to make an entire modern assembly to + or - 0.001 precision... and these monuments are bigger and more precise than that!
