Sorry about that, Im working on a post now.
EDIT: my bf might come over and if he does i might be delayed till tomorrow afternoon
EDIT2: And by the way, im absolutely fascinated with daily life of prehistoric and other not-so-pre-historic peoples of this time period so if anything is long winded im sorry. Im not an expert or anything its jsut little things i pick up from the books i read :p (and its not anything important its like how they kept their shit trenches from stinking and other random little thing)
EDIT3: By firestone I mean flint, which i looked up and was a part of human life in prehistoric times so Im assuming they would know of it too, :V
