How Did It Start?

I love books but wonder how it all atarted Before there were printed books the were hand written scrolls of some kind but they require a written langyage . How did this language develop? How did we communicare ? where did languages come from ? How did we go from spoken words to written ones. Do we really know how this happened?
Communication wwithout written words would be so difficult
