Granted you can also argue the same about Incans and to some extent Mesoamericans, so it’s kind of debatable.

This entire discussion stems from the fact that the word "civilization" is essentially defined to fit the societies people already consider civilizations. There are technologically, politically, and socially complex societies that aren't "civilizations". My recommendation is to avoid the word entirely. Trying to use it scientifically leads to confusion.
Requirement for a writing system is an arbitrary condition. A lot of civilizations, especially in that region, have strong oral traditions.
Also would a knotted thread record keeping system count as writing?
