When you look from the perspective of a scientist at the universe, it looks as if it knew we were coming. There are 15 constants—the gravitational constant, various constants about the strong and weak nuclear force, etc.—that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people.
