Galaxies, in terms of the scientific definition, don't exist. The things that we call galaxies are ULM (unknown luminous matter), which consists of predominantly CFM (crystalline firmament material).
If it Looks Like a Galaxy
The Space Narrative
The peer review driven popular science space narrative (SciPop) starts with the premise that the Bible is wrong and the Earth is billions of years old. It continues with the idea that stars are distant suns and galaxies.
Relative Quantities are not the Quantities
When the sun is less massive than the Earth, planetary and stellar bodies have gravitational relationships with each other that have the same relative proportions, but at a different scale.
Synonymy
We have to take a step back and remember that we are on popular science turf (SciPop) when we start talking in their terms about the cosmos. SciPop wants you to believe that the stars are distant suns and galaxies.
Isaiah or Math?
Stars falling to Earth is unfulfilled prophecy. A standard belief among Christians is that God is faithful and true. He always keeps his promises. All prophecy has either been fulfilled or it will be fulfilled.
Riding the Heavens
The idea that God or his agents may physically visit the Earth by riding on a piece of heaven may seem ridiculous. However it appears that a section of firmament is used like an elevator to travel between heaven and Earth.
The Brightness of the Firmament
The creation of gravity and formation of the firmament was to establish a place, heaven, where God would dwell in perpetual light because the firmament is bright like the sun, as we see from Daniel.
The Three Heavens
Given that the apostle Paul specifically refers to something called the third heaven it's not a stretch to conclude that there must also be a first and a second heaven. We need to know what they are.
Two Years Before the Earthquake
Amos prophesied the coming judgment of God two years before an earthquake. How did he know that it was coming? Amos was a herdsman and probably spent his nights outside. Did Amos see something in the heavens?
Absolute Dates
Radiometric dating has been contrived in such a way as to make it look as if the "dates" it calculates for rocks are absolute. Absolute means that the dates are separated on a timescale which is known.
