Of course, it is, in no way, physically impossible that there are interstellar interlopers out there (there are, of course), only that such things are unusual. Again, the burden of proof would be on those who would suggest that the object was artificial in nature, as opposed to a natural object that simply got ejected from its parent star. If the latter, however, then there must, statistically, be a lot of these things out there.
I just find it to be suspicious, but suspicion is not evidence.
