Russell explains that Fenny, who is sitting in a drugged state in the back seat of the car, became delusional after worldwide mass hysteria, in which everyone hallucinated 'big yellow spaceships' (the Vogon destructor ships that 'demolished' the Earth). He hitches a lift with a man named Russell and his sister Fenchurch (nicknamed 'Fenny').

He has been gone for several years, but only a few months have passed on Earth. He appears to be in England on Earth, even though he had seen the planet destroyed by the Vogons. While hitchhiking through the galaxy, Arthur Dent is dropped off on a planet in a rainstorm. A song of the same name was featured in the 2005 film adaptation of The Hitchhiker's Guide to the Galaxy. Its title is the message left by the dolphins when they departed Planet Earth just before it was demolished to make way for a hyperspace bypass, as described in The Hitchhiker's Guide to the Galaxy. Meanwhile, the poor Babel fish, by effectively removing all barriers to communication between different races and cultures, has caused more and bloodier wars than anything else in the history of creation.So Long, and Thanks for All the Fish is the fourth book of the Hitchhiker's Guide to the Galaxy 'trilogy of six books' written by Douglas Adams. Most leading theologians claim that this argument is a load of dingo’s kidneys, but that didn’t stop Oolon Colluphid making a small fortune when he used it as the central theme of his bestselling book, Well That about Wraps It Up for God. ‘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. ‘Oh dear,’ says God, ‘I hadn’t thought of that,’ and promptly vanishes in a puff of logic. It proves you exist, and so therefore, by your own arguments, you don’t. ‘But,’ says Man, ‘the Babel fish is a dead giveaway, isn’t it? It could not have evolved by chance. 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.’

“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 the final and clinching proof of the non-existence of God.
