If our vital organs work we have LIFE and if atleast one of our vital organs don't work, we don't have LIFE.
As to what gives us life...basically we have evolved from other more primitive organisms and if you go way back to the beginning of life you will find that originally life came out of non-life... After all we ourselves are made up of a lot of 'non-living' elements like calcium and iron for example. Life orignally came out of non-life, because what is life but simply non-life that has a nervous system...can think....has emotions...organs...etc, etc, etc?
One theory I've heard of is that an asteroid crashed on earth before life existed, (atleast on earth) and some asteroids are thought to carry quite large amounts of some form of protein. Might be BS but who knows. I don't believe it but I accept it as a possibility, I don't know of any evidence to support such a claim yet. Maybe someone else has info on this?
