Stand aside Darwin and put 'God created the heaven and the earth' on hold, because today there is a third theory to contend with.
Dave Willis from Bognor, makes the staggering claim that life on Earth started as a result of inter-galactic travellers discarding a half eaten cheese and pickle sandwich into the primordial soup two billion years ago, and that this in turn acted as a catalyst, starting all of creation as we know it.
"I know it sounds a bit far-fetched" admits Terry Pratchett fan Dave "But Zoraf from the 12th Quasi-dimension has sent me a sign and verily it is true" insisted the long-haired pony-tailed freak.
"When you think of it we are all related to cheese and pickle, aren't we?" asks the total wassock.
We contacted BBC boffin and xylophone-playing mentalist Patrick Moore for a comment.
"Well of course it's an interesting theory but I'm afraid it's absolute nonsense" gabbled Patrick with his trademark pop-eye gleaming and his hair all over the place.
A spokesman for NASA told The Spoof:
"This is the most preposterous nonsense I've ever heard in my life and I believe that there's not so much as the slightest shred of evidence to corroborate this claim"
Dave was last seen heading off to Ben Nevis to await Zoraf arriving to take him off to the 12th Quasi-dimension where they have a stag party to attend.
