To be completely correct we don't even know if the Earth exists....Eshnar said:That's no proof of emotions nor suffering as we call it. Animals are surely aware of what happens to their bodies, and that's a physiological fact. But that's it, as far as we know. Do they feel "pain"? Surely they realize they're been attacked, or they're wounded, or they have a sickness, and react accordingly. That's not a proof that they feel what we feel, although it is surely a hint. It wouldn't be unreasonable to imagine that one day (not even too far away) we'll have robots full of sensors able to be completely aware of their internal and external body state. Perhaps even able to "be scared", meaning being able to run from potential dangers. Or being able to care about humans and interact with them. Does that mean those robots would feel "pain", or "fear", or "empathy"? Surely not, by the very definition of what we mean by "feeling".
To be completely correct, there's no actual proof that we all have a consciousness either (this is the paradox of the "zombie" - not those of the movies though ), although just the thought seems very silly. On the outside we can only see actions. There's just no way to tell, unless we really "crack" the mistery of consciousness at a physiological level.
