If that's true, show your work.
If the exact same energy is converted from mass->light->mass again, in the exact same form (same electron spins, etc), then at what point was it destroyed? E=mc^2, which tells us that light and matter are just two different forms of the same phenomenon (or, at least, *might*, which is good enough for a hypothetical argument).
What about the simple replacement of atoms in your body from year to year. If 50% of the atoms in your body have been replaced, have "you" been destroyed and recreated?
