If you followed 'due east' on a compass you would travel in a large circle around the north pole.

If you wen't "true east' as a straight line, you would actually eventually be going 'due south' and would hit the firmament wall over the Ice Wall in antarctica

the waters above the firmament is actual space but God controls it. It is where the waters from the Flood came from. We have literally bombed it before (Operation Fishbowl, supposedly with a nuke, if they actually exist) but it is impervious to our weapons.

The stars in the waters above are really angels that are SINGING just as the Bible describes. Their light is caused by sonoluminescence (an effect where light is created by sound in water).

'Planets' are wandering stars that did not obey God. That is why they are all named after false gods that go by many names.
