Narrator: Mankind,probably the most mysterious species on our planet. A mystery of open questions. Who are we? Where do we come from? Where are we going? How do we know what we believe to know? Why do we believe anything at all? Innumerable questions looking for an answer,an answer which will raise the next question and the following answer will raise a following question and so on and so forth. But in the end,isn\'t it always the same question and always the same answer?
讲述者：人类，也许是这星球上最神秘的生物，一个充满着疑团的奥秘，他们是谁？从哪儿来？往哪去？怎么确定自以为知道的是什么东西，为何会相信事物？数不尽的没答案的疑问，即使有答案也只会衍生另一个疑问，下一个答案又衍生下一个问题，但最终是否只是同一个问题？同一个答案？
