Hi there, Megan. I don't think that the question of an Overseer is completely outside the realm of science. A scientist or rational thinker, I believe would be willing to entertain convincing evidence of the existence of an Overseer. If it's an interventionist "god", then it seems to me that it's very possible and even likely that it could present me with some good scientific evidence for its existence, that is, evidence I could show as repeatable, predictable, or even simply visible to me and other rational thinkers. Maybe "god" will never choose to demonstrate such evidence, but it doesn't mean that scientists are not willing to be open to it if it shows up. Some more than others, of course!
I love the "turtles all the way down" story, but I don't think merely because the question hasn't been answered, that it's unanswerable. Problems people considered unsolvable two hundred years ago are now cleared up in grade school!
What is a "strong anthropic principle"?
(I see you've added a wiki for me on that; thanks.)
