How did they presume they completed this work?
At that elevation, the number of workers is expounded, due to the lack of oxygen at that level. How many men DOES it take to move 1 ton, vertically at that elevation? It CAN'T be the same as at sea level...
What technique did they use to surface those stones?
Stick your neck above the pool of ignorance you are sunken in to and you'll find the answers.
The quarry from where the Incas took the stones was located, there are stones in several stages of carving and removal; unfinished walls were found with stones at various stages of placement and fitting. The techniques, wich were demonstrated, by the way, were surprisingly simple and effective. Stuff of geniuses, I would say.
As for the altitude, well, here's one more example of how your ignorance cripples your extrapolations. People practice sports at that altitude. Try checking the Copa Libertadores da América, a Latin American soccer competition. All it takes is your body getting used to it. Coca leaves may also help.
So, quit that arrogant attitude of yours, start realizing you know much less than you think. Your limited experiences and poor knowledge are not enough for many extrapolations.
I'll bet they DON'T know. If ALL those stones are andesite, then there was an advanced technology at work there too. That stuff isn't soft, and take massive amount of energy to shape.
Wrong bet. All it takes to carve a material with a given hardness is another piece of material with the same hardness. So, guess what can be used to carve andesite (wich by the way is a rock composed o several minerals, each one with its own hardness)?
What it looks like was that the stones were stacked into place, within molds, then softened and smashed together like so much clay, then hardened again. THIS would indeed be an 'advanced technology', that we lack today.
This is nothing but an argument of ignorance and arrogance. YOU don't know how they could made it. YOU think it LOOKS like and this is far from being equal to "is". Stop watching woostuff and go check that documentary on Macchu Picchu.
These works are anything but 'easy' or even possible without modern/advanced technology.
Bullcrap.
Those people lived centuries ago and had no advanced technology. They were more much more skilled, intelligent and smarter than you. Deal with it.
a) I can only provide you MY findings, and encourage you to gather your own, in regards to how much time it takes to remove how much stone.
Your "findings" are nothing but the product of poor skills, ignorance and arrogance. Those guys lived hundreds of years ago and beated your skills and intelligence. Deal with it.
You say they used modern technology. Prove it. As I wrote before, each tool leaves at its product an unique signature. Show these marks. Marks produced only by modern tools such as high-velocity rotary drills with vidia bits, for example.
Ever wondered why there are no works published showing these marks?
