人类之光-蓝色的星球

At the dawn of time, the universe explodes into being. With it, every atom in our bodies, Countless galaxies, innumerable stars.

And around one of them, a blue planet, Our earth. No other known planet has both an atmosphere and liquid water. The conditions needed for life.

13 billion years after the universe begins, A unique species is born. Mankind. Now, in the grasslands of East Africa, We begin our struggle against the odds.

A band of brothers. Their leader, the genetic ancestor of all mankind.
