把这一句，留给此刻的你
We don't know why we are here and the context of our role in the universe, and the thought of an infinite universe. It's something the human mind can't really grasp. It's statistically impossible that there's not life on other planets.
我们不知道我们为什么在这里，不知道我们在宇宙中所扮演的角色的背景，也不知道无限宇宙的想法。这是人类大脑无法真正理解的东西。从统计学上讲，其他行星上不存在生命是不可能的。
