Those are all good points, but it is not necessary that the Dyson builders are native of the star where they are building a certain sphere, right? Of course it is still much more reasonable to assume that this is just some unknown natural phenomena, but it is exciting that there is a small possibility that it is not. If they do exist, I agree with a point you made some time ago that they would probably not need anything from us or our planet, and thus not represent a threat. I guess the only possible reason why such an advanced civilization could be interested in us would be scientific curiosity.
