Perhaps you have something profound to communicate here, but you're not doing a great job of getting it across.

As an example, in response to "very few have achieved anything like the Incas," I asked for something specific to establish a frame of reference, and you replied with something that can be summarized more or less as "very few have achieved something like the Incas."

As to your second point, this is remarkable. Nobody has disagreed. But it's not extraordinary. Not every culture has to be agrarian. Not every culture has to be written. Draft animals, arches, wheels. These are one way to solve specific projects problems. They aren't the only solution. The Incas, through remarkable ingenuity and effort, solved those problems differently. Again, remarkable but but extraordinary.

It feels to me like you've asked and been answered, and for myself at least, it sounds like you've sort of dug in and want to be found on this hill of Incan exceptionalism. I personally find their exceptionalism exceptional, as exceptional as the many other exceptions that have been discussed in the thread so far.
