Lyrics
Our whole universe was in a hot dense state,

Then nearly fourteen billion years ago expansion started, wait... And 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 a 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 leave but they were late

And they all died (they froze their asses 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 pause then 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!
