>>56747444...yeah, they pretty much did, you absolute shit for brains. starting over 3000 years ago. listing some highly efficient industrial process doesn't prove shit - if i post the same flow chart about modern commercial farming does that mean that the romans didn't know how to farm? they didn't build a lot of pocket watches either, so i bet they didn't know what metal working was, right? i'm sorry your mom didn't drink enough during her pregnancy to kill you outright, profound retardation must be hard to live with.
