And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day. And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.(Gen 1: 6-10)
And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth. (Gen 1: 16-17)

This analogy needs careful handling because creationists are adept at ignoring the point of an argument and attacking a caricature of it instead. So, to be clear from the outset, this is not a claim about what the Bible says. It is a simple thought experiment about how we test claims against reality.
Suppose someone wrote a book in which he claimed to give an accurate description of the Bible. In it, he said the Bible consisted of only four books, two in the Old Testament and two in the New Testament; that it had only 120 pages; and that the entire story was about Adam and Eve and their sons, Noah and Moses.
How would we test those claims?
The answer is hardly complicated. We would get a Bible and compare the claims with the book itself. In other words, we would test the description against the reality it claimed to describe. And once we had done so, only two serious conclusions would be available: either the author was deliberately lying in order to deceive his readers, or he was so ignorant of the facts that he simply invented them. What we could not sensibly conclude is that the Bible was wrong for failing to match his description of it.
That, in its simplest form, is how science works. A claim is tested against reality. We begin with the assumption — the null hypothesis — that there is no meaningful difference between the claim and the facts. We then look. If the evidence shows a real difference between the claim and the observable facts, the claim has failed the test. It is not reality that must be adjusted to rescue the claim; it is the claim that must be rejected or revised.
This may sound like a “Janet and John” explanation of basic science, but it is remarkable how consistently creationists get even this wrong. They have a book which, when read literally, makes claims about the age, origin and structure of the universe. With modern science, it is a straightforward matter to compare those claims with the real universe. When we do that, we find that the description and the reality are not merely different, but radically, irreconcilably different.
Yet instead of concluding that the ancient description is wrong, creationists conclude that the evidence must be wrong. The facts are not judged against reality; reality is judged against the prior demand that the Bible must be right. This is not science. It is wishful thinking dressed up as certainty.
In effect, creationists believe their beliefs trump the evidence.
So what claims does the Bible make about the age and structure of the universe, and how do those claims compare with observable reality?
To be fair, the Bible gives no explicit numerical age for the universe. The familiar young-Earth figure of about 6,000 years comes from calculations based on biblical genealogies, most famously by the 17th-century Archbishop James Ussher, who placed creation in 4004 BCE. Modern young-Earth creationists often stretch this to somewhere between 6,000 and 10,000 years, not because evidence requires it, but because the older figure is now too obviously absurd to defend with a straight face.
The Bible is more explicit, however, about the structure of the universe as understood by its ancient authors. It describes a world in which the Earth lies beneath a firmament, or dome, which separates the waters below from the waters above. The sun, moon and stars are described as lights set in this firmament to illuminate the Earth. Elsewhere, the stars are treated not as distant suns and galaxies, but as objects that can fall from heaven and be trampled underfoot. This is the cosmology of a small, human-centred world, not the universe revealed by astronomy. (Genesis 1:6-10; Genesis 1:16-17; Daniel 8:10)
So how does that ancient description compare with what we find when we actually look? Take, for example, this tiny fragment of the sky visible to the Hubble Space Telescope:
