You are too dismissive. It seems that one can conceptualize natural selection in terms of a multidimensional fitness function that modulates over each iteration. Then one might ask whether, given our current understanding of processes of inheritance, the complexity we observe could have evolved by those processes given the age of the earth. If not, then our understanding of evolution is either incomplete, or our evolution was 'helped along' by an intelligence, which btw is not an appeal to supernatural intelligence, but alien intelligence. Naturally these last are unlikely, but that is not the point. The point is that the question is legitimate.
