Yes, but they are spiritual beings. I saw the blue and red kachina in vision during revelations. I also saw the blue kachina with my own eyes. It streaked across the sky from horizon to horizon; east to west in about a second or two. I though it was a shooting star for a moment but it's tail never diminished the whole time. It appear to be pure plasma of electric blues and whites. Once it hit the west event horizon it all vanished in synchronicity leaving a quick steam vapor that vanished even quicker.
