I see, you are of the opinion that in the Ice Age, caves in what is now France were so rare as to be singular, and that the only alternative was a skin tent? Shit you're stupid. Stop bothering me, since you're too stupid to talk to, since you're too stupid to understand that a region with one cave often has many caves, and that some caves are more suitable to long-term habitation, due to multiple characteristics, such as ventilation for cooking fires, a source of clean fresh water nearby, it has to stay dry when it rains (snow is different than rain you mook), and it helps if it's somewhere where the womenfolk can forage for additional food. Also, in Europe, the primitives also built homes from sod or wood or combinations of both, even in prehistoric times. It's not like wood is a modern invention. A cave used as a hunting camp compared to a cave used as a Winter home is like a tent compared to a house. Would you prefer living in a tent or a house for the Winter? Now, I've wasted more than enough time on your lame stupid ignorance. Go read a book, faggot, or I will block your dipshit ass.
