5,000 years ago, the ancient Egyptians wrote things down using a picture writing called hieroglyphic.1:50
The people who did the writing were called scribes.1:57
The scribes had a problem, however.2:00
The ancient Egyptians wrote everything down, absolutely everything.2:03
Although hieroglyphics were very pretty, it took time to write in pictures.2:07
Scribes needed a faster way to write things down.2:12
So they created a new form of writing called demotic script.2:16
Now they could write much quicker, but the skill of reading in hieroglyphics was lost.2:20
And for hundreds of years people didn't know what they meant.2:25
