Apple

In the beginning there was a tree
All hung with apples, sweet as can be
What harm an apple, one apple from the tree
A little knowledge will surely set us free

We crossed the oceans, we learnt to fly
Unpicked the helix, forgetting why
We split the atom, our flag unfurled
A little knowledge will surely light the World

We left the garden to claim the Earth
Weighed up creation to calculate its worth
Struck out for heaven, built towers to the clouds
A little knowledge has surely made us proud

What harm an apple, one apple from the tree?
