Today, we visited Amsa prehistoric site for learning about prehistoric age. Prehistoric age is divided into 3 ages by the materials that they used. First, stond age is when people used the tools made by stone. In stone age, the stone is made by chopping, but the stone is grinding in Neolithic age. Next, Bronze age is when people used the bronze tool and likewise, people used made by iron in iron age. Because the prehistoric age is the period before written record, there are no proof that knowing about the definite history about prehistoric age. But we can know by using the thing that we can find easily. The example of this is comb-pattern pottery. By considering comb-pattern pottery, we can know that from Neolithic age, people start to do agriculture refers to farming. The reason why they need comb-pattern pottery is to store the fruits and crops and cooking. Because they are uncomfortable, they made the point-bottom to keep them in the ground. So, I think today was the chance that finding the wisdom of ancient ancestors. I expect the next class that learing about Gogoorye, too!
