Dare I say it's a Space ship coming in through the waters above and then coz they have the Keys to the Gate in the firmament they can come inside and then the ship changes form?

I don't think it's going out as the firmament here is our own special quarantine!

I know there are more tech descriptions - I have just read lots of books which have these firmament covered worlds and so assume that is predictive programming and if we trust our own eyes.

Why don't these guys know what it is if it is one of our craft?
