Who had the system of writing Aztecs Mayans or Incas?

The system of writing was primarily developed by the Maya civilization. The Maya used a complex system of hieroglyphics to record their history, religion, and daily life. In contrast, the Aztecs had a form of pictorial writing, but it was not as sophisticated as the Maya's. The Incas, on the other hand, did not have a writing system; they relied on quipus, which were knotted strings used for record-keeping and communication.
