fascinating, but it does frustrate me that archaeologists often have so little common practical sense.
Why would people living in the houses fill them so full of discarded bones, pottery and flint? They weren't big houses and the inference is that people were living and sleeping in them. The Neolithic people used every scrap of everything so why did they leave such a litter? Partying? But someone would clean up such a bounty unless there were other motives. Sigh! More stories forming!
The archaeologists in question are pretty damn good--you're dissing people I know personally. We're talking Barry Cunliffe, for crying out loud, among others, like Sarah Champion, who was lead staff archaeologist for the Orkneys dig.
I also assume that you're basing your judgment entirely on the news paper articles, which don't really go into a lot of detail, and that's a little unfair.
Part of the standard structure of these houses, found in Orkney as well, is a midden trench inside the walls, and, because just as in medieval houses, the floors were covered with rushes or sand, then that was swept into the trench, and, eventually removed to an outer midden, often when the house was rebuilt or enlarged or sometimes, seasonally.
Much of the refuse is from the central fire pits--which were used for decades.
After the houses were no longer lived in, and walls were removed and reused, stuff got stirred by the environment and more stuff was dumped, some of it obviously ritualized, often in cthonic pits--they've found La Tene style bronze pins, for instance, that were ritually damaged.
And yeah, they're not big houses but they're designed for communal living and the bed frames are designed for more than two people. Given the so called Stone Henge Archer, it's increasingly looking like this was in fact a ritual center for a very large number of peoples, from a very disparate geographic area.
