[Verginius Rufus]

They found fragments of cuneiform tablets--not clear how much of value can be gleaned from them. When archives are found (as at Ebla) sometimes a lot can be learned.

It would be interesting if they could manage to extract human DNA from any of the bones (not clear how much they found of human remains) and see how the population compares to present-day populations of the area. That would be before Indo-European speakers arrived (Kurdish is an Indo-European language) except perhaps the latest periods of habitation.

Not sure what you’re asking exactly, but the earliest ‘civilization’ in that region was probably Semitic, or possibly Indo-European. I’m not sure I’ve ever heard of other alternatives.
