I went to Amsa prehistoric site today.

I'd like to tell you about shell mounds.

Neolithic people lived near the riverside. They farmed, fished, and ate shells. They threw away shells. The shells made mounds which helped us to learn about the people in those days.

The mounds serve as a time capsule from the Neolithic era. After looking around there, I felt like a lucky boy. I think that the people in the past looked smart. They already knew how to farm, fish, use tools like hooks. If they had not known anything, we couldn't develop a lot now.

I hope many people learn a lot of things from the past.
