Our whole universe was in a hot dense state

Then nearly fourteen billion years ago expansion started

Wait! 

The earth began to cool

The autotrophs began to drool

Neanderthals developed tools

We built a wall

We built the pyramids

Math, science, history

Unraveling the mystery

That all started with the Big Bang

Bang! 

Since the dawn of man is really not that long

As every galaxy was formed in less time than it takes to sing this song

fraction of a second and the elements were made

The bipeds stood up straight

The dinosaurs all met their fate

They tried to leap but they were late

And they all died

They froze their @$$3$ off

The oceans and Pangea

See ya, wouldn't wanna be ya

Set in motion by the same Big Bang

It all started with the big... Bang! 

It's expanding ever outward, but one day

It will cause the stars to go the other way

Collapsing ever inward, 

We won't be here, 

It won't be heard

Our best and brightest figure that it'll make an even bigger Bang

Austrelopithicus would really have been sick of us

Debating how we're here

They're catching deer

We're catching [bad word] 

Religion or astronomy

Encarta, Deuteronomy

It all started with the Big Bang

Music and mythology

Einstein and astrology

It all started with the big bang

It all started with the big... 

Bang!
