What am I?

Savater says that if an extraterrestrial comes to the earth and he sees our daily life, it would probably think that everything is part of me, like my house, my car, clothes, even cell phones. We would try to explain to this being that our possesions are not part of us, that we are our body, but what about the thing(?) that allows us to be unique?... I think we are more than just flesh and bones, we have that "something" which makes us different from inanimated bodies. We feel anxiety, sadness, happiness, we can laugh! Many people would say we have a soul. I think so too, I feel like this thing called "soul" is the one that is constantly connecting our movements with what we call reality, concreting what it wills, like a force that cannot be seen nor touched, but you know its there. There have been many critics about this, and maybe people is not wrong or right, but close to the answer. Let me explain, from ancient times people have narrated about events which involve the recognition of the spirit of bodies, like ghosts, astral voyages, etc. And they sometimes agree that the body misses like a "sparkle" when it looses the soul, so how can people perceive this? is it a kind of "matter" which we know nothing about it? There are so many things we don't know we can't be sure of anything. I think at least my body is connected with that something we haven't yet identified, and also that it belongs to like a Force that is greater than only one body.
