The theory of panspermia states that life didn't start on Earth, but instead was brought here.

胚种论声称生的起源不在地球，在地球之外。

Oh, I just realized what panspermia means.

噢，我好像发现胚种论很污。

Now hold on, before you start to think that ancient aliens did it, panspermia actually refers to the transference of bacteria.

等一下，你千万别以为人类是古代时外星生地球上的，因为胚种论实际上是细菌转移说的引用。

But the idea that life was delivered to Earth on space rocks, which goes by the awesome name panspermia… well there's just no proof it ever happened, and it doesn't really explain the origin of life anyway.

但是，生由太空岩石地球的想法，也就是人们所称的“胚种论” … … 根本没有任何证据证明它曾经发生过，而且它也不能真正解释生的起源。
