Complexity of the Universe

It is interesting in a way that as science progresses, it finds that our universe keeps getting more and more complex.  This week, a new subatomic particle was confirmed.  Though I do not pretend to understand everything involved (I have long since been out of that game), I am impressed at the things we are able to discover.  The thing that really gets me is that as we discover the universe to be more complex than we imagined, we can still look at the world and say that it all happened by chance.  There are so many presuppositions that must be stacked on top of each other to make for a completely natural universe that it is astounding that would be our conclusion.  And yet it is.  Quarks, neutrons, protons, etc. are so complex that the vast majority of people can't understand them without years of study.  Yet it is the assumption of many people that these all came together through random/lucky processes to form matter and eventually life.  Bravo, that is an incredible act of faith indeed!
