Yeah I think it was the mastery of Agriculture about 10,000 years ago that finally allowed us to create cities and hoard populations in a single location which subsequently lead to writing and the passing on of knowledge and technology to further generations.

What I find most interesting is that Neanderthals were alive like 30,000 years ago and apparently burried their dead before we did and also had superior tools and larger brains, we just outnumbered them like 10 to 1 so they eventually got annihilated, it's an interesting thought that we possible aren't the best of our species, Iirc we are like one of 7 species of humans and the only surviving type.
