We live because as Anthropic Principle postulates that our Universe seems to be designed to fit our existence.

我们之所以能够生存，是因为如人择原理所假定，这个宇宙为了适应我们的生存而专门设计的。

One answer is the anthropic principle: the universe we see has to be hospitable, or we would not be here to observe it.

其中的一个答案是人择原理the anthropic principle：我们所看到的宇宙必然是热情友好的，否则我们就不可能在这里去观察它了。

I won't try to explain the anthropic principle, as I am not sure how to do so without making it sound tautological.

我不会试图去解释人择原理，因为我不知道怎么说才不会使它听起来像是无谓的重复。

Scientists and philosophers who think so are subscribing to what's called the "Anthropic Principle"–the suggestion that nature is exactly the way it is in order that it will eventually create us.

科学家和哲学家认为这些可以归结为“人择原理”： 正是大自然这样地演化才最终创造出人类。
