I’ve read a lot of archaeology magazines and it seems that everything they find was used in some fashion in a religious ritual. It’s rarely a kitchen or a plain old pot or bedchamber, etc.
Not sexy enough for the donors, I reckon.
Small figurines (like “fertility statues” and whatnot) could easily have been used to advertise cathouses, or were presents for mom from little kids. The idea that the famous stone age cave paintings were made by kids is starting to catch on as well.
