Neanderthals built mystery underground circles 175,000 years ago

It is always fun to watch conjecture presented as fact:-)
"They worked by torchlight, following the same procedure hour after hour: wrench a stalagmite off the cave floor, remove the tip and base, and carefully lay it with the others.
Today we can only guess as to why a group of Neanderthals built a series of large stalagmite structures in a French cave – but the fact they did provides a rare glimpse into our extinct cousin’s potential for social organisation in a challenging environment.
Gone are the days when we thought of Neanderthals as crude and unintelligent.'
I suppose the artists signed their names which is why we "know they are Neanderthals" and Cro–Magnons for instance.
I like the definitive "torchlight" assumption as opposed to skilled blind workers.

In an off hand way it could be their way of a religion, just guessing.
