Historians were able to decipher hieroglyphics after the discovery of the Rosetta Stone.
It provided the first chance to understand Egyptian Hieroglyphics writing by providing the same text in Hieroglyphics, Demotic, and Greek. Both the Greek and Demotic could be read to find out what was being said on the stone, the Hieroglyphics could then be compared and analyzed for patterns (similar to the way codes and cyphers are broken).
Hieroglyphics
This is not true. Many thousands of people today can understand and read Egyptian hieroglyphics.
The Rosetta Stone is the key that helped scholars decode some Egyptian hieroglyphics.
The Rosetta Stone had three different languages one of which was Greek, and another was hieroglyphs. Historians already knew Greek so they used it to sort of decode the hieroglyphics.
Most scientists probably don't think anything about hieroglyphics. Historians know that they are a form of pictorial writing used by the ancient Egyptians.
