I had told all ready told you that I haven't been off topic. I know nothing of scots etc and therfore haven't posted anything about them. I have thanked others for posting about the subject. but thats different.

On the subject of Neanderthals I have posted.

With no evidence that they were builders of stone structures any import from me would be pure speculation. Not something I'm comfortable with but, here goes.

They may have built structure that have been swept away by the ice and the tide of humanity, but obviously there is not evidence of such. Of course no evidence doesn't mean anything other than no evidence. But, If we look at areas in Europe where neanderthals settled and the ice didn't reach, then there still isn't any evidence of them building structures, even in the areas that mankind were quite 'thin' on the ground.

So it look to me like it was unlikely that they built structures, but as I have said, speculation and opinion.
