Writing Changed Everything

Writing began as a tool for accounting — and then reshaped every part of human civilization.

• The earliest tablets from 3400 BCE list barley, sheep, and beer
• The rebus principle — using signs for sounds — made abstract thought writable
• Cuneiform was the oldest known script, but our alphabet grew from a separate line
• Writing enabled law, science, literature, and knowledge passed down across generations

It also created a new profession: scribes trained for years in schools called edubba, copying texts and learning mathematics.
