My feelings exactly. And one reason I've not commented beyond amplifying a cuppla other peoples' comments, such as Jimit (& others) who've asked about soil samples.

On that point, I also must say that I find it very hard to believe that with all the excavations that have been made, nobody's come across that evidence of the detritus of milling. (Or not commented on it.)

I also find it hard to believe that the stones were ever smooth enough to work in the way you describe.

As far as I'm concerned, come back when there's some evidence.
