Peace Between People

We breathe the same air.
We share the same skies.
But then in the end.
everyone dies.

There's no difference between us,
exept our race.
We're all the same inside,
and we have the same face.

So why there is war?
That, I don't know.
We're just fighting ourselves,
and no friendship can grow.

So why not have peace?
Please explain.
Why not have comfort,
instead of pain?

We're all related,
like nephew and neice.
So why can't the world
be filled with heavenly peace?
