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
A 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 asses off!)
The oceans and Pangaea
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 pause and start 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!
Australopithecus would really have been sick of us
Debating how we're here, they're catching deer (we're catching viruses)
Religion or astronomy (Descartes or 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!
