We used to be content with a piece of charcoal

Sketching on walls in a gloomy dark hole
Then we put our strengths into building castles
Now we?re a tribe of destructive arseholes
Crawled on all fours our hands replaced paws-
As if we foresaw we would open doors
From trees we made oars to explore the shores
We were madly obsessed with the great outdoors
But not in that order I hear you moanin
But what can you tell from a fossilised stone
In a pile of bones the truth becomes clear
We Pioneered schemes just too severe
Way back then there were few concerns
Find meat to eat, chop wood to burn
And learn to avoid the sabre-toothed tiger
Now our biggest enemy is laser-guided
Too much weight draped on our shoulders
The land that we knew stood firm to hold us
Colonisation is what they sold us
So someone decided we needed soldiers
Destructive forces is what they told us
Invent the engine replace the horses
We stretched resources to drive our Porsches
And now it's all gone wrong
