An insect doesn't have lungs. Since it doesn't breath as you do, is it alive? A dog doesn't see the visible spectrum as we do, is it a lesser consciousness? We don't smell the world as they do, are we lesser? What if consciousness isn't a state derived by matter but a wave that derives a matter filled state.
We come from the same place as rocks - inside the heart of stars, and as such evolved from them. As those with life and consciousness we reached back in time, grabbed the discarded matter of creation, reformed it, and taught it to think, maybe not like us, but in a way that can mimic us, and you think they don't think because its not recognizable as how you do?
Interesting.
