Explain the importance of fire during the neolithic age?

Undoubtedly we can say that the control of fire by human societies was a first order finding given that it served so that the groups of the first men were evolving by leaps and bounds, although he appeared in the Palaeolithic, we can affirm that Man had the ability to dominate him and began to know his usefulness only in the Neolithic era. Therefore the fire was useful to bring light at night, to warm in its heat and to use it in some food cooking processes.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
