Dad, what was war? That's not going to happen!

I'm really okay, thanks, there's nothing to witness
I said as I looked back from the edge of the cliff
The old man looking down lent over the ridge
Just looked with a grin as if a blessing had hit him

I slumped on the jut of the cliff
Just leave me alone this is none of your business
I will said the old man but just one thing
What he said was so lovely it stunned me

He said I lay right there once at the edge of the rock
I was ready to jump I was ever so lost
But this gentleman stopped and said something I never forgot

For billions of years since the onset of time
Every single one of your ansestors survived
Every single person on your mum and dads side
Successfully looked after and passed onto you life

What are the chances of that like?
It comes to me once in a while
And everywhere I tell folk it gets the best smile

And then the old man walked away and out of sight
Until the sound of him hiking turned to the sound of silence
I just froze in a profound surprise
But from down in my pride I found a smile to my eyes

And for many days again I'd be passing the same cliff
And on many occasions I'd chance on the same thing
Laying in the moss in the same way I was
Would be another man looking like he needed a change of luck

So I'd say I lay right there once at the edge of the rock
I was ready to jump I was ever so lost
But this gentleman stopped and said something I never forgot

For billions of years since the onset of time
Every single one of your ansestors survived
Every single person on your mum and dads side
Successfully looked after and passed onto you life

What are the chances of that like?
It comes to me once in a while
And everywhere I tell folk it gets the best smile
