They meant this, which refers to copying the state of a particle into another (already existing) particle

https://en.wikipedia.org/wiki/No-cloning_theorem

And basically, about consciousness, what they said is true if our brain state fundamentally depends on quantum effects (which I personally don't believe, as I don't think evolution is sophisticated enough to make a quantum computer)

>as I don't think evolution is sophisticated enough to make a quantum computer

Well, evolution managed to make something that directly contradicts the 2nd law of thermodynamics, and creates more and more complicated structures (including living creatures as well as their creations), instead of happily dissolving in the Universe.

And this fact alone hasn't been explained yet.

		This is a bad explanation (or a non-explanation). 1. Why exactly life is attempting to build complex structures? 2. Why exactly life is evolving from primitive replicative molecules to more complex structures (which molecules on themselves are very complicated?) 3. Why and how did these extremely complicated replicative molecules form at all, from much more simple structures, to begin with?
