We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only way that they can prerve their history is to recount it as sagas--legends handed down from one generation of story-tellers to another. The legends are uful becau they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. The sagas of the people explain that some of them came from Indonesia about 2,000 years ago. But the first people who were like ourlves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from. Fortunately, however, ancient men made tools of stone, especially flint, becau this is easier to shape than other kinds. They may also ha小学生日记200字
