One of the most amazing things about our world is the delicate balance required to sustain it, that is, to have a universe capable of producing and sustaining life as we know it. In the book The Creator and the Cosmos, astrophysicist Hugh Ross points out twenty five factors that must all exist within very narrowly defined ranges for life of any kind to exist. Just one of these is the number of electrons. Unless the number of electrons is equivalent to the number of protons to an accuracy of one part in 1037, or better, then galaxies, stars and planets could never have formed. To get an idea of just how sensitive this is Ross asks us to imagine covering the entire continent of North America in dimes all the way up to the moon. Then do the same thing on a billion other continents the same size as North America. Now you have 1037 dimes. Now imagine that just one dime is painted red. You have mixed it in will all the others. Now take a friend a blindfold her and stand her in front of those of those billions upon billion of dimes covering a billion continents and piled to the moon and ask her to pick one out. Her chances of selecting the red one are one in 1037. These are the same odds as the ratio of electrons to protons being at the precise level required for life, and this is just one of many parameters that must be so finely tuned. Ross and many other scientists believe this points to a universe which has been carefully and skilfully designed by a Creator.
