Is that a good analogy? "There’s a very interesting analogy that might help us understand the ‘prior-to-big-bang’ universe. Pick the smallest real number that is bigger than 0. Somehow one can always pick one that is smaller than yours... Hence asking what is the smallest number greater than zero does not make any sense. There is no smallest number that is bigger than 0. Big Bang is something similar. There was no first moment.”

Since we do have a 0, we also have minus numbers that grow bigger once you count backwards.
