who is the u in universe?

""If someone asks you a question "Who are you?" What shall be your answer? You will say I am.... Either your name or your profession. I say my name, my designation, my profession. Hence, all these are 'mine', they are not 'me'. My name is given to me, where I was born was given, my parents -did I choose them or given to me and who is the giver? we just receiver's? Then Who am I? who are you exactly.
Each poem will make you question you""
