I'm not sure how your post stays on the topic of your title—you seem to wander off quite a bit as the post goes along(?)—but as for your title, it is important that believers recognize the human element in the writing of scripture, something the WTS and other religious conservatives do not really do. Even if one wishes to view the content of the Bible as divine, the books themselves were written and preserved down through time by very fallible human beings. That is a weighty factor in the corruption you bring up in your title.
Your other points seem a bit "corrupt" themselves: when the meteor that crashed into what is now rural Arizona many years ago and destroyed the lives of countless pretty, fragrant plants, innocent "nice" animals, and perhaps humans, was that an example of that object of space "keeping to their orbits just like vehicles follow lane-discipline on a busy express highway (as though submitting themselves to some unseen authority)"? Examples of other natural phenomena behaving in unpleasant ways (lions brutally tearing apart deer or other "nice" prey, poisons of certain reptiles and insects slowly tormenting those infected with their toxins to death, erupting volcanos scorching all beings in their paths, naturally occurring toxic gases choking animals and humans, and so on) can also be cited. The natural world is full of such things. What sort of "unseen authority" do these things demonstrate?
BTW, I am a theist/believer, a deeply thinking one.
