This object is clearly not a one-off. The people who made it made similar objects, perhaps many similar objects, and probably made other objects with similar skill requirements. This is the only one we have, however. What else did they make? What sorts of tools, clothing, weapons, houses, wagons, etc? We can only speculate. Still, I doubt they were what we would consider cavemen. These were civilized humans living in a fashion most humans today would recognize as human. We have to go back quite a bit further to find anything I'd call "the dawn of man". Keep in mind, there are tribes living in "neolithic style", with little or no clothing, no tools besides rocks, etc. still today. The existence or even domination of such people doesn't determine the timing of the "dawn".
