You are making the point that this is probably not a 15,000 yr old TOWN, per our current understanding of the term.
Hunter-gatherer tribes usually don't create "towns", nor do they have the time and resources to have carvers etc., except in the most rudimentary ways such as the flint knappers and basket weavers.
Agriculture allowed for the introduction of such divisions of labor. The rise of towns, villages and hamlets came after that.
I hope the story is true. It would be marvelously fascinating to know that at roughly the same time that there were folks blowing ochre over their hands onto cave walls, there were others living totally different lives.
I'm still wondering abou the "name" part. After 15000yrs, what did they do, ask the old timer down the road what the name of the place was?
They didn't give a name. They did say it was found near a modern town and gave that name.
