In one of his lectures, KN Rao, the renowned jyotishi, stated that Brahma creates new models of humans every year here on earth. If that's the case, then these humans are coming from the various sectors, or nakshatras, of the universe. So, it is conceivable that there are humans who come from the Pleiades or the nakshatra of Krittika who are members of this forum right now.
