Everything starts somewhere, although many physicists disagree.
But people have always been dimly aware of the problem with the start of things. They wonder about how the snowplough driver gets to work, or how the makers of dictionaries look up the spelling of words. Yet there is
the constant desire to find some point in the twisting, knotting, ravelling nets of space-time on which a metaphorical finger can be put to indicate that here,
here is the point where it all began ...

(Terry Pratchett, Hogfather, 1996)
