They could be IF someone can come up WITH a better explanation. It only makes sense for Science to use the best explanation we have for the information and evidence that is available for us to examine. 2Peter1:20 "Knowing this first, that no prophecy of the scripture is of any private interpretation."
The Bible says they are called stars, and they are said to give off light. But the Bible does not really describe how they exist within the universe beyond the fact that they give light. We do not know exactly what ALL of them are and where they are by distance exactly. Sure, they are most likely large hot balls of light like our sun. But we are basing this off our knowledge and or observation of our own solar system. Seeing we have not really been there, we cannot say with 100% certainty what ALL of these light sources are like. Also, stars may be closer than we think, as well. How so?
Ever looked backwards through binoculars?
If you have you will be aware of a simple trick of optics, just as a telescope can make things appear closer.
The optical properties of our solar system and galaxy can act just like the backwards binoculars and make objects "appear" further away.
The galaxy could be like a lens and we are inside it.
This means when we look at stars and galaxies that are not in the milky way we have no real idea how far they are from us.
There is a size luminosity diagram designed to decide what type of stars we are looking at, but stars have bubbles around them that act like lenses. How do we know we are looking at the surface of the lens or the surface of a star?
When you consider these "lenses" have different properties and the two lenses can "factor" into each other, we might actually be a lot closer to the stars than it looks.
How much closer?
Well the further away from our solar bubble you get the more the apparent distance is distorted.
So not only are the closest objects (other stars in the milky way) a lot closer than we think but stars and possible galaxies outside the milky way may be much closer than we think.
The further out you go the higher the compounded errors are and the larger the universe looks.
What about expansion?
Well if we are in an expanding lens looking out into the universe,
We would see the universe expanding due to the bias from the expansion of our local bubble.
If the galaxy bubble was expanding the whole universe would "appear" to expand.
We measure large distances with light, but light can effect the perceived distance if it is being effected by a lens; So if we are in a lens, how can we use light?
Light can be affected by lenses and cause all sorts of image artifacts, distortions, magnification, and dislocation between image and mass.
All these problems have very complicated answers.
