Matter can be created and destroyed, energy cannot be created or destroyed in a conserved system.

If you present matter with a precise quantity of its antimatter counterpart they'll both annihilate; the total energy of the system will be conserved, but the matter will be destroyed.

Conservation of mass, not matter.

There is a difference between mass and matter, the former can be created and destroyed, the latter cannot since it's a property of stress-energy.
