It's the theme song for a TV programme, "The Big Bang Theory". The song tells us all the history of the Universe in less than two minutes.

It's the best theme song I've ever heard for a TV programme. It´s a fast, happy song. If you like science, this is your song.

Barenaked Ladies (often abbreviated BNL or occasionally BnL) is a Canadian alternative rock band. The band is currently composed of Jim Creeggan, Kevin Hearn, Ed Robertson, and Tyler Stewart. Barenaked Ladies formed in 1988 in Scarborough, Ontario, then a suburban municipality outside the City of Toronto.

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, unravelling the mysteries,
That all started with the big 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 pangea
See ya, wouldn't wanna be ya
Set in motion by the same big bang!

It all started with the big BANG!

Australopithecus would really have been sick of us
Debating out while here they're catching deer (we're catching viruses)
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!
