You said "rocks don't talk to me and think and act intelligently." But a coma patient who is conscious would be unable to talk and act in an intelligent manner. That does not means that they are not conscious.

So consciousness does not require externally observable behavior. That was my point. So a rock could be conscious for all we know..

Also, If you are irritated by my "crap", why don't you stop replying? Are you paid or somehow obliged to correct every crap talker on the internet or something?
