that's a pretty good question...humans seem to be the only creatures (that we know of of course) in this simulation that have achieved the level of consciousness of which you speak
But why do you say so? I'm talking about the consciousness _experience_ not the behaviour.
I have no evidence that you experience consciousness anymore than I have evidence that a dog does too. How can you or a dog prove to me that you experience consciousness?
All I know is that I am conscious and I doubt I'm that special, and that's why I have faith that others are conscious too. I don't see such a big difference between humans and many other animals.
From what I gather we don't even know in detail how single celled creatures make decisions! Testate amoebas build distinctive shells for themselves, putting particles in the right places. Some can even decide to not reproduce if there's not enough material for daughter cells to have their own shells. Maybe they experience consciousness too, just limited in their capabilities and senses?
