In each human coupling, a thousand million sperm vie for a single egg. Multiply those odds by countless generations, against the odds of your ancestors being alive, meeting, siring this precise son, that precise daughter... to distill so specific a form from that chaos of improbability, like turning air to gold... that is the crowning unlikelihood. The thermodynamic miracle. But the world is so full of people, so crowded with these miracles that they become commonplace and we forget.
I just performed a miracle. I ran a random number generator from 1 to a trillion and got 788,126,838,503. 1 in a trillion chance of that happeneng. In fact I did it a hundred times and got a number with a 1 in a trillion chance every time. But no one cared.
