Andrew Denton: When you see this sort of stuff, do you ever get a sense of God's pattern?
Sir David Attenborough: Well, if you ask...about that, then you see remarkable things like that earwig and you also see all very beautiful things like hummingbirds, orchids, and so on. But you also ought to think of the other, less attractive things. You ought to think of tapeworms. You ought to think of...well, think of a parasitic worm that lives only in the eyeballs of human beings, boring its way through them, in West Africa, for example, where it's common, turning people blind. So if you say, "I believe that God designed and created and brought into existence every single species that exists," then you've also got to say, "Well, he, at some stage, decided to bring into existence a worm that's going to turn people blind." Now, I find that very difficult to reconcile with notions about a merciful God. And I certainly find it difficult to believe that a God -- superhuman, supreme power -- would actually do that.
