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? Who am I? Who am I?
Tell me, tell me, who am I?
Who am I? What's my name? What's my name?
Who am I? Who am I? Who am I? What's my name?

I know I'm asking a lot, I want to know, who am I? Who am I?
What's my name?
