They could also be descriptions of musical scales, or maybe weaving patterns, base-encoded numbers perhaps....who knows, really? Also Egyptian writing goes back perhaps 5000 years. That is a Semitic language so it stands to reason that it too would likely fall in the same category. Anyway I do love these kinds of archeological finds nonetheless. Interesting to see if Gobekli Tepe yields even older instances of written script? (If they ever get around to a proper excavation, that is! IIRC the site is currently not open to researchers.)

Egyptian is afro-asiatic but not semitic, like Berber, somali and others

Egyptian writing is old but it is not (primarily) alphabetic.

Yes kind of a hybrid, isn't it?
