The ancient Egyptians invented written scripts because they believed that recording and communicating about religion and government matters was very important. Hieroglyphics is the most famous and commonly used writing system in ancient Egypt. The hieroglyphics were used mainly to maintain beliefs, ideas and history of the ancient Egyptians. TA very important discovery which led us to deciphering the meaning behind hieroglyphics was the Rosetta Stone, which is a rock stele and had hieroglyphics, Demotic script, and Ancient Greek written on it, and since we knew how to read Ancient Greek and not hieroglyphics, since the message inscribed on the stone was the same in all three languages, we were able to decode the language slowly but surely.
