Writing in Ancient Egypt [Hieroglyphs]
First and most amazing Egyptian invention ever; that pure Egyptian tool helped mankind to record their beliefs, heritage, and history.
Egyptians have invented the first writing in human history, started with some signs, marks, and pictures from the surrounding environment. This type of writing was called by ancient Greeks hieroglyphic meaning the holy inscription or holy writing which was used for religious purposes.
Then they developed another cursive type of writing called Hieratic which was basically used by priests to summarize and explain holy inscriptions.
Demotic, everyday writing, used by local government and individuals.
Egyptians also devolved the first alphabet known to man called "Sinai Alphabet" which is the base of all western alphabets today. They have also added Coptic which is still in use in Coptic Church's liturgy and prayers.
