Aboriginie only makes sense because the physical nature of the aliens that Raël claimed to come into contact with was similar to the characteristics of the aboriginies:

"The extra-terrestrial human being was a little over four feet tall, had long dark hair, almond shaped eyes (maybe even soniferous ones?), olive skin, and exuded harmony and humor." -- http://www.rael.org/rael_content/rael_summary.php

Even then, the "aboriginie" idea is a stretch. I thought that's what I was hearing at first too, but it doesn't make as much sense as "Apparition, he"
