Lyrics The Big Bang Theory - Greatest TV Themes

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 mysteries
That all started with
The big bang! Hey!
