6.2.9.
Hieroglyphic writing existed long time ago. There were writings with pictures and different languages in some symbols too. They had to use symbols and pictures, because that time they didn't know about letters and words. It wasn't even invented yet at all. Sometimes it was hard for them, because they had to write on a rock which is shaped oddly. Also, when they wanted to talk they had to write rather than speaking verbally. Meaning, instead of conversing, these people had to write on rocks on the spot to communicate with one another.
