We can read of things that happened 5000 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 preserve their history is to recount it as sagas-legends handed down from one
generation of story-tellers to another.These legends are useful because 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 these people explain that some of them came from
Insonesia about 2000 years ago.
But the first people who were like ourselves 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,because this is easier to
shape than other kinds.They may also have used wood and skins,but these have totted away.Stone
does not decay,and so the tools of long ago have remained when even the bones of the men who
made them have disappeared without trace.
