Babel Fish

So, GN told me to post something here, something intelligent. So here is my attempt at that...

In 'The Hitch Hikers Guide to the Galaxy' there is a really good quote about how God cannot exist.

'Now it is such a bizarrely improbable coincidence that anything so mindbogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as a final and clinching proof of the non-existence of God.'

'The argument goes something like this: "I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."'

'"But," says Man, "the Babel fish is a dead giveaway isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED."'

'"Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic.'

'"Oh, that was easy," says Man, and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.'

I think you can easily apply this to some of the other fascinating creatures and things on earth and in the universe, even ourselves. Discuss
