And the Aurignacian also used bone for tools. In either case, your original point is refuted. You should study a little science before making broad and easily-refuted pronouncements.
Actually you made my assertion stronger...those beings were alledgly around over 25000 years ago...so it went from 25000 yrs ago using bones and rocks to 20000 years later using rocks and then in less than 5000 years we went from using stick and stones to flying to the moon...
