Today,i went to the national museum of korea.I learned about the palithic and neolithic.First,at the ice age,it was very cold so they move to the cave.Even they go inside the cave,it was cold.so they made a fire.Fire was a big change of the history.Now the people have to hunt

to eat.So they get the two stone, and cut it with another one stone.We call it chipped stone.(and one of the famous chipped stone is hand axes.)Then the neolithic age come.Now, the peoples are not living in the cave.They made a pit house.And they made near the ocean or lake.It is because to catch the fish.Ofcourse,they didn't eat only fish.They get the acorn and(they made the polish stone)polish and put it in the pottery.Then baked with the fire and eat it.
