Identifying

Can you please identify yourself?

Identify myself? and can you tell me how can i do that?
only by producing a chemically manufactured piece of paper can i be identified?? 
is my presence not a better evidence of myself.

but how do we know that you are what you are claiming to be?

So how can a meagre document prove myself ,if not me ?

these are the queries which abuse the existence of oneself.
but unfortunately no can escape it!

So please identify yourself!
