The discovery of the Rosetta Stone lead to the people to it, approximately 1930 BC, every Canaanite, Egyptian, and the Greeks could read what the Rosetta Stone had said we couldn't necessarily read it until it was discovered i don't remember by who but when it was, we found out what it said That's what the discovery of the Rosetta Stone lead to how it is today. Additional Info: The main 'benefit' or knowledge gained by decoding the Rosetta Stone was being able to decipher hieroglyphics. Up until the discovery of the Rosetta Stone, it was assumed that hieroglyphics was a pictographic language, i.e. a picture of a bird represented the word 'bird'. However, after the discovery (and subsequent translating) of the Rosetta Stone, it was determined that hieroglyphics was a phonetic alphabet, where a picture of a bird might stand for the character "B" (that's not accurate, I'm just making an example). If you have ever used Wingdings in word before, you get the idea of what hieroglyphics are: a pictographic symbol that represents a single character.
The Rosetta Stone is important because it allowed us to study Ancient Egyptians and their language. Without it, we would know nothing about Egyptian language, the ruler Ptolemy V., or even Ancient Egypt itself.
