So he saw no proof that life arose spontaneously...how interesting. I suppose he expected to be out in the forest with his magnifying glass and witness a mushrooom turn into a spider and when that never happened, well obviously there's a designer with a capital D out there. Good lord.
The ironic thing is that his assessment "I saw no proof that life arose spontaneously from nonliving matter" is actually a pretty good summation of the argument for evolution! Isn't it the bible that asserts that life (adam) arose spontaneously from nonliving matter (dirt)? The evidence is pretty strong that a very simple form of "life" (that we might not even call life where we to see it today) arose gradually from observed chemical processes that occurr when energy is pumped into an environment similar to primordial earth. I hardly think that something that took 500 million years (after the end of the late heavy bombardment) could be considered as happening "spontaneously." The subsequent 3 Billion or so years of evolution that it took to get us to our current level of biodiversity and complexity is even less spontaneous. The only one that asserts that life arose spontaneously is the creationist saying that god just did it one day.
