Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.

Why can't matter be creAted from energy?

In any reaction, or process, both the amount of mass and the amount of energy remain constant. You might say that mass has energy, and energy has mass. Any mass or energy "created" during a reaction was already present previously.
