- For most of our planet's history,
在我们星球的大部分历史中 - land has been inhospitable to life.
陆地都不适于生命居住 - A bleak and desolate realm...
一片荒芜 - more like the surface of the moon...
更像是月球表面 - than like Earth today.
而不像今天的地球 - It's hard to imagine
很难想象 - how anything could ever make this hostile place its home.
任何生命 会在如此充满敌意的地方定居
