In neolithic times, the people learned to farm and grow crops to eat. This was significant because it changed human history, they could stay in one place and no longer have to hunt for food and risk their lives.
This job is so helpful.
In the Neolithic times people also learned how to build house and they where permanent because they could grow crops now, they know how to farm.
I need some tools.
They learned to make communities and live together like a big family. If they didn't get along, communities were important because if the people didn't live together, it would be harder to survive.
They did jobs and worked together to get what they needed to live. If they didn't work the work wouldn't be done and they would have trouble.
They traveled hundreds of miles to get what they needed when they run out of something or just needed it and din't have it in their area. If they didn't trade, they wouldn't get the things that they need.
