10,000 years ago we were cavemen who lived off the land. We only had what was accesible in nature. Now we have cars, iPhones, and computers. I’m assuming everything we have now is composed of the same matter cavemen had access to. How did we get all this stuff?

Question

Apologies if this is a repost.

I just don’t get how the Earth went from being entirely nature to having the iPhone I’m typing this on. And like where did we get the internet? And how do we take pictures?

ETA: A lot of great answers but I’m not really asking about people. More about the stuff. When I picture the Earth 10,000 years ago I don’t see anything that could make my phone.

We build on what the previous generation did. We use their tools to make better tools (technology). And so on.

Social relations are also technology that builds up over time. The ways in which we work together– supply chains, command hierarchies, ideologies– become more complex and enable more specialization and more expertise.
