If having a conscious experience is our only frame of reference of what it’s like to be a bunch of particles, then on what authority do we assume it could be otherwise for any other bunch of particles? What should it “be like” to be a rock? I’m assuming nothing special is going on, and what we experience is exactly what it’s like to be a bunch of particles. There is no mystery. There is nothing that needs to be answered.
