Oh nothing much. I just like being in a community!
Paleolithic Age people had an unsteady food supply because they would waste all their days of hunting for food to travel to the next area. Farming changed life because Neolithic Age people stayed in one place so they could farm to have a stable food supply for them.
Ok. I found flowers. Now my job is to get them back home for Timmy.
Paleolithic people had natural caves as their temporary home. The disadvantage of this is that they have to collect all their stuff and move every few weeks. Neolithic people had a permanent shelter which changed life because now, you can farm for your food in a permanent shelter.
Ok. So the other kingdom wanted wheat, so i'll give them it for flint.
With permanent homes, can come many things. One of them is the production of communities. This changed history because with the responsibility people held, came jobs and, eventually, modern society.
With jobs, produced goods and materials. This changed life because using materials, humans could build massive structures and empires. Also from this came trade. New jobs came later, like money counting.
Trade was the friendly act of giving someone what they wanted for what you wanted. This changed history because now people could get what they wanted from far away. From this also came, trust.
