abiather, I think you are mixing a number of separate ideas which are probably best to address individually.
Evolution provides a satisfactory answer to your first point as to why certain organisms may or may not change over time. It is an impersonal mechanism that is not man-made and does not require belief for it to work.
The rest of the points you listed (e.g. religion, social institutions, economics, governments, etc.) may be better analyzed under the framework of social/cultural evolution, semiotics, philosophy, psychology, and other man-made constructs. And, to be fair, these may operate in a similar way as evolution. This is what many are trying to do in the field of memetics, which at present is a weak theory but serves as an interesting analogue to evolution.
However, you then seem to add God into the equation and try to tie (and/or explain) those ideas together. I think? Perhaps to you the above don't make sense without the idea of a God/Designer/Prime Mover. I think this is true for many theists.
As an atheist, I will be happy to add God to the equation if it ever becomes necessary.
