How about from the people who study chance ? The issue with rare events is that you can never estimate the probability curves. This has the strange result that each one looks unique, complex and very much non-random ... despite potentially being very common, simple and random. We have one example from an unknown distribution. You can always read a lot into it's exact properties ... but there's nothing to be read, because we don't have the variation on those properties. So this could have been a very common run-of-the-mill interstellar asteroid ... and it could have been an alien explorer. We don't know, and we probably won't know. Well, I guess in the second case we'll eventually realize.
