Well....Maybe

The point is that they are applying the term "civilization" to it on the assumption that what they see is writing.  Right now I think that is a bridge too far based on what they have uncovered but certainly worthy of further investigation.

The question is what you call a civilization. Look at the picture I posted - it's hard to say, this wasn't made by a civilization. Same goes for the cave paintings. I'm sure you're aware of how artful they are. That's civilized and doesn't require writing to call it that.

The point is, for a combined effort, such as creating a monument, like Stone Henge, a combined effort is required. And for that you need to be organised in one way or the other.

Well, as far as I understand it, the jury's still out on the one you posted. But I wouldn't be surprised. There's always something new cropping up, which I consider very exciting, regardless of the outcome.
