Ancient Stone Constructions

Some old constructed stone structures in present day South Africa have been dated based upon the erosion of the stones. The estimate says they were built sometime between 200,000 and 160,000 years ago. This is much older than any other known ancient civilisation, much more than 100,000 years older.

I doubt that the estimated age is correct. It is not just that it is so much older than any other known civilisation, or that there are no sources mentioned from scientific papers. It is also that humans did not have dogs until about 40,000 years ago. No known human civilisation have been without dogs. Dogs are an essential part of human civilisation. I think humans can do much, but not have a whole civilisation without dogs. We are this important for humans, aren't we?
