I remembered Grandam telling me about an early Old Earth scientist, one Charles Darwin, who had come up with one of the early theories of evolution or gravitation or somesuch, and how--although raised a devout Christian even before the reward of the cruciform--he had become an atheist while studying a terrestrial wasp that paralyzed some large species of spider, planted its embryo, and let the spider recover and go about its business until it was time for the hatched wasp larvae to burrow its way out of the living spider's abdomen.
