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.

As inaccurate as it can be at time, the anime/Manga Dr. Stone does really well at explaining how the basics turn into advanced machinations that can advance everything further.
