This is probably one of the better ways to understand how neolithic people lived. I visited a really interesting place last year that does similar reconstruction archaeology, https://en.wikipedia.org/wiki/Castell_Henllys https://en.wikipedia.org/wiki/Castell_Henllys At one point I was in one of their reconstruction huts and they had a large open fire in the centre to keep warm. I was surprised to find they had no chimney system so the hut was full of smoke. If I recall correctly they said it was because the hut was made of wood so they couldn't build a chimney and it would be a fire risk if they put the fire closer to the edge. I questioned whether it was bad for their health that they were breathing in so much smoke and one of the researcher there said, "I don't know, but we'll find out". It's an interesting iterative approach to learning about history.
