What if we covered the entire North American continent with dimes 239,000 miles deep, which would extend all the way to the moon. Now pile dimes from here to the moon on a billion other continents the size of North America. Now, paint one dime red and mix it into the billion piles of dimes and blindfold someone and have them choose just one dime on the first try. The odds he would pick the one dime are one in a trillion, trillion, trillion - and that gives you an idea how breathtaking it is to have just this one aspect of the universe so delicately balanced. And there are dozens and dozens of other examples like this.
