Then nearly fourteen billion years ago expansion started. Wait...

The Earth began to cool,

The autotrophs began to drool,

自养生物开始起哄，

Neanderthals developed tools,

穴居人发明了工具，

We built a wall (we built the pyramids),

我们建了长城（我们建了金字塔），

Math, science, history, unraveling the mysteries,

That all started with the big bang!

一切都由宇宙大爆炸开始。
