* Sign languages are not a monolithic entity: There are hundreds of different sign languages around the world, each with its own history and development.
* Sign languages have been around for a long time: Evidence suggests that sign languages have existed for as long as humans have needed to communicate visually. This likely predates written language.
* Sign languages evolve: Just like spoken languages, sign languages change and develop over time.
What we do know:
* Ancient origins: There is evidence of sign language use in ancient civilizations, including depictions in Egyptian hieroglyphics and Roman mosaics.
* Deaf communities: Sign languages developed organically within Deaf communities as a primary means of communication.
* Modern sign languages: Many of the sign languages used today evolved from earlier forms, often with regional variations and influences.
Therefore, it's more accurate to say that sign language has a long and complex history, with roots stretching back thousands of years.
