It is true. Like the “If they were so smart why didn’t they have the wheel?”. I am sick of hearing that...
Well, they did indeed know about the wheel, but they had no beasts of burden to pull heavy carts and wagons. And with the terrain of the Andes mountains they would still be trying to finish those roads to be wide enough. So why?
They made their roads just big enough for what they had. Alpacas and Llamas which are very feet footed and agile. Take 40 of them to pull a cart with wheels and it would still be impractical on the terrain and hills of the Andes.
So no need for the wheel either... Not needing it doesn’t make you ignorant or stupid. It makes you practical and wise with using what you have and making the best of it. :)
Werl, yeah ok. CIties in Asia have little carts pulled by human beings. Flatter, sure, but are you telling me they couldn’t fashion a llama-width cart that would be a whole lot more efficient than people carrying all their crap? Maybe they just felt they needed the exercise?
