You are self aware because you are aware that you are here ,right now, that you have hands, brain, legs, dick, hair, etc, etc. You are aware.of what you are doing, you are aware.of what you have done in past. But machine is just programmed to do things or react on outer influence. There is no understanding why machine is doing it, machine don't know that it's doing anything. believers would say it's our soul, and that's why we are like this. But I have watched documentaries and still science is trying to answer WHAT IS councesnes.
