No Name

No Name
I know I'm asking a lot
Forgive my persistence
But I want what I haven't got
Proof of my existence
Look up - what do I see
Mankind looking like me
And I know it's not because I am
mankind's hero

At times it's good to hide
Get swept along with the tide
But I've suddenly seen that I'm one big zero
No name - tell me, who am I?
what's my name?
what's my name?
