The word “evolution” evokes ideas of advancement, and improvement, and ascension, but “in practice” evolution is to accidents as a beach is to grains of sand. That’s evolution; it’s not a matter of being better, or even adapting, it’s just a matter of stumbling forward and whatever happens happens. On the physics side of things, “energy life” sounds like a cool idea, it’s not really a possibility (as far as we can say). A “ball of energy” that’s independent of matter isn’t really a thing. Evolution is a process of accidental baby steps, and turning into an energy being, even assuming it’s possible, is more of a leap.
