The Law of Conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant. Similarly, the Law of Conservation of Energy states that energy cannot be created or destroyed, just transformed from one form to another. We can categories everything in this world under matter, energy and conscious/mind/soul. We already came to the conclusion that matter or energy cannot be destroyed. Then why is it so hard to assume that conscious/mind/soul can also not be destroyed?
