This is all a red herring. Life is definable. Even if you believe there is no distinct boundary (I believe there is a clear definition) you still have clear categories of living vs non-living. You are still faced with the complexity of the simplest free standing life form. This needs to be explained. It can not be.

Here is a definition of life. http://en.wikipedia.org/wiki/Life#Definitions
