Adam

Adam understood that he doesn't know too much things. Nobody explained to him that after the trees there's a lowland, that the floating ball in the sky is made of fire or that you can't capture it.
He doesn't know that what he feels is hunger, but he knows that when he puts something in his mouth the pain will stop.
Adam calls himself, he explained to others that his N.A.M.E, the way they'll call only him, is A.D.A.M.
He pronounces it again, tasting it, before jumping off the branch and getting to the plain and becoming the first man.
