So it's just a coincidence that the term is also utilized on Earth? [Bristling a bit at the insult] I have nothing to dispute it, or confirm it currently. There are a myriad of galaxies in the universe, but technology isn't advanced enough to extend to all it's reaches. [With a huff] Though I'm doubtful that there are any little green men out there... that's at least a work of fiction..

Considering I doubt that some of them even have a concept of reality, it would be a wasted effort.
