A long time ago, there were the prehistoric and historic age. The prehistoric age was the age before written records.

 The stone age is the prehistoric age. It divides into two periods . one is the palleolithic age and the other is called neolithic age. The reason why these two are separated is because in the neolithic age, people started agiculture. It's surprising that people figured out a way to farm. In the stone age, people used stones for their tools. I think the reason we have technological advancement in our society is because these people found their ways to survive and thive in the world.

 I wonder if people of today live with nothing but nature, would they be able to survive? I don't they can do as good as the people in the past because the people in the present had all the things ready for them.
