Not sure i necessarily believe the genetic mutation part but overall great post. Not all genetic mutations are necessarily bad, and genetic mutations can be small scale. Totaling up into a large change that is observable after many generations. And of course Darwin's theory of survival of the Fittest stands strong in regards to the last sentence of point one. If this creature with a bad leg were really unfit to survive. IE (not being able to outrun predators, get food, etc.) It would die and the mutation would be lost anyway. Darwin observed the species on Galapagos and noticed that on each island similar species had different characteristics, based on where they were located what they had to eat etc. so the theory of evolution is partly observable under the right conditions. but just because something changes from how it originally was doesn't disprove any heavenly creation theories either. In fact, I think somewhere down the line humanity will learn that science and the supremely powerful force of creation are really one in the same. As we gaze upon the miracles of life we seek to understand, not just our origins but the entire world around us. in the words of Arthur C. Clarke "any sufficiently advanced technology is indistinguishable from magic." with 'technology' as a blanket term that quote can be applied to all things that seem supernatural. Science grounds us in reality but without our imaginations and intellect we wold cease to advance, and learn and we would never be able to definitively answer the question of weather there is a God, we might not even have the concept at all. What i'm trying to say is just because there is a God doesn't mean what we call science isn't what was used to develop the universe. for all we know God could be an amazing scientist, with knowledge we have yet to attain. will definitely check out the link tho it seems really interesting.
