Each human female has about 300,000 eggs during the fertile period of her life. Each male ejaculation has about 300 million sperm. Thus each conception contains about a hundred thousand billion different possible combinations of DNA. In other words, there are a hundred thousand billion unique and different human beings that could result from each procreation event. Only one of those possible combinations led to each of you reading this article at this moment. Here’s a way to visualize that extremely tiny fraction. If you took a very long ruler that stretched from here to the planet Pluto, one inch of that distance would be you. The rest of the distance would be other possible human beings that could have been, but never were. Each of us has won a lottery with a hundred thousand billion different players.
But the article does have a nice little add-on I’ve rarely seen:
From the distant past, billions of years ago, to the distant future, billions of years ahead, the universe will never see another one of you.
Usually I’m comforted by the vastness of the Universe rendering my very being literally meaningless, but then sometimes I can’t help but wonder if maybe I really am the center of the Universe; why else would I even be here?
