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?
