This scene shows the cave days and hunter gatherers. Hunter gatherers hunted and work hard for they're food,they hunted for food to keep themselves from starving and for some of them that had children they took care of themself and they're children. Hunter gatherers mostly lived in caves and shelter from the stone age.
Between the eighth and eighteenth century, the tools for farming basically stayed the same and few advancements. The agriculture revolution was a period of technological improvement and increased crop productivity. The shelter they had was houses and farms.
Life improved by how to shelter got stronger and how the food source got better and how public got more better also. I included a town to show how the shelter and everything else improved.
