I see you've leapt from talking about indigenous Americans to sub-Saharan Africans since you know very well that they have perfectly reliable water sources. But okay, we'll go with this.
>What major work projects would they need to more mass amounts of stuff to be dumped out again.
Any possible major works. You were just claiming earlier that these people couldn't make great works because they didn't have the resources or means. It's circular logic. The existence of tools like wheelbarrows would allow for great works. I'm curious exactly how you think these technologies appeared among proper humans in Europe and Asia. Divinely bestowed?
And how about carts? Africa has plenty of domesticable animals, as does Central America. (Here's where you insert your cope about how those animals can't be domesticated, and your proof is that they weren't, therefore they can't be.)
>So if you lived in 1500's Central America as a native, what's the point in having a wheel when nothing can get through the jungle and everyone is all helping do the work?
Central Americans had paved roads at that time.
