Great Green Arkleseizure
The Great Green Arkleseizure is a fictional deity mentioned in Douglas Adams's The Hitchhiker's Guide to the Galaxy.
Although not offically considered a god, the Great Green Arkleseizure is nonetheless the creator of the universe according the the beliefs of the Jatravartid people of planet Viltvodle VI.
The Jatravartids believe that the universe was sneezed out of the nose of the Great Green Arklseizure, and they live in permanent fear of a time they call 'The Coming of the Great White Handkerchief'.
The Great Green Arkleseizure can be used as a response to the Cosmological argument as an equally plausible theory to explain the origins of the Universe. The Coming of the Great White Handkerchief can be seen as a vision of the end of the universe that is no less unlikely than the one presented in the Book of Revelation.
Since the Great Green Arkleseizure is not considered a god in the truest sense, it can also be seen as an atheistic (and parodic) explanation for the existence of the universe; accepting a creator, but denying that the creator is divine, or indeed had a plan of any kind.
