I don't know if it is because i am not english speaking but i have
hard time
to get your point and to see the correlation with my  post that you
are
answering to.
Where did you get the 2,5 milions years of fire domestication,? .and
evidences of fire pit is not evidence of cooking
a lot of the native tribes of north america were still eating some of
their
meats raw when the occidentals came
and used fire for heat.
I often sit around a fire and eat my meat raw .. and throw the bones
in the
fire. archeologists in the future might deduct that i was using fire
for
cooking but i don't .
