Why are we here?

These are the most enduring of questions.

这些问题源远流长。

And it’s an essential part of human nature to want to find the answers.

而人类的天性就爱探索答案。

And we can trace that ancestry back.

追根溯源，

Hundreds of thousands of years to the dawn of humankind,

时间定格在几十万年前，人类文明出现之刻，

But in reality, our story extends far further back in time.

实际上，我们的故事将延伸至最早的年代。

Our story starts with the beginning of the universe.

从宇宙的起源说起。

It began 13.7 billion years ago.

But today, it’s filled with over 100 billion galaxies,

而今，宇宙中已形成逾千个星系,

Each containing hundreds of billions of stars.

每个星系拥有数以千亿的星球。

In this series, I want to tell that story.

在本节目中，我将向大家讲述这个故事。

Because ultimately we are part of the universe.
