So the distinction is that your origin story takes roots into physics (signature energy), while mine takes roots into metaphysics (prime undefiness).

Honestly, I don't think energy would mean much in high-end metaphysics, since it is essentially the birthplace of all concepts and definitions, including that of "energy".
