Just my own perspective: as one who believes God is responsible for the origin, complexity, and diversity of life, this article makes me chuckle. The theory of evolution as an explanation of the origin of the major taxa of life really paints us into a corner from which it is difficult to wiggle out. In my opinion, the panspermia/alien origin hypothesis (and its persistence as an explanation in some respected circles)…

You don't see a distinction between life on another planet and supernatural phenomena...?
If you assume the major groups of life evolved from common ancestors, the fossil record doesn't offer a lot of help to fill in the early details (i.e. transitional types). Also, you have the problem of the origin of the first single-cell organism.

My point is that insisting on it being an alien life form that seeded life on earth (as opposed to the God hypothesis) is kind of begging the question. Philosophically, what is the difference between an unknown alien life form and God as the origin of life, other than different starting assumptions?
