Mystery #1Tier 2stars and sky

Why do the stars seem to join up into pictures like a hunter or a bear?

Look up on a clear night and the stars seem to sketch shapes: a hunter with a belt, a great bear, a giant W. People all over the world have named these pictures for thousands of years. But are those stars really joined together up there, or is something else drawing the lines? Why do we see pictures in the dark?
