imo "intelligent designer" is appled retrospectively by both creation and evolution (when evolution is seen as a progression)
If we see both terms as closed paradigms then there isn't much difference between creation and evolution imo. But if we see them as open concepts then they are both rich sources of ideas and meaning. For example creation describes an important part of the process of evolution and evolution (when evolution is seen as a progression) describes another important aspect of the process of evolution from a human perspective. But neither is the be all and end of the process of evolution imo.
edit: the concept of creation can tell us that we are all gifted but progressive evolution can tell us that only some of us are gifted as things stand today.
