On the assumption of the accuracy of the record:
I don't find any fault with it mentioned in that tribe's documents. It was oral transmission at first, but then Moses wrote it down. When he wrote some of the pages of the Law, he referred back to it, to details about marriage or about the 6 days (leading into laws about the Jewish sabbath). It was taken to be accurate. Several Psalms vouch for it, including the 'speaking-into-existence.' They make no mistakes about other events, so we may assume them to be solid on early Genesis. Then you have Christ a couple millenia later, validating a number of things inside the early (oral) chapters of Genesis, including creation. Finally, you have Paul validating it (this same person who wanted to stop the Christian movement, but who was Jewish) quoting them (early chapters).
So we must at least ask, what are we going to find, now 4 millenia removed?
Now, on a certain detail, I can walk through some points about why I said 'our local galaxy'. In Genesis, Moses had a stylistic structure, something like this:
1, section title
2, existing background
3, new action
4, restatement or summary
There are probably 10 of these in Genesis, which is partly why the most familiar scholars have little doubt of its integrity.
Gen 1:1 Title: In the beginning (God created) the heavens and the earth
1:2 existing condition: the earth was formless and void
1:3+ new action: God creates forms for 3 days (to solve the formlessness: land, sea, atmosphere and nearby objects in space) He then creates 'things' to go in each form: animals/plants, marine life, birds. It is now formed and filled.
1:31 restatement or summary: it was all done (all systems working); it was very good
The reason for allowing for some time is that 'formless and void' is a mysterious condition. The expression appears in a prophet's description of Jerusalem ruined later on. The ruined city is said to be that way. We really don't know what happened in early Genesis, but it is possible that other things were going on, and not good, and stopped before the week we know as creation. We don't know how long either, which speaks to your point.
This is not a fluke of the Hebrew scripture. It compares with many other origin-accounts (cosmologies) from the Ancient Near East: Persian, Hindi, etc. As if to say, yes, there was that other primal world, but the Lord God dealt with it and created this one quickly and wanted man to represent him on this earth. The world as created was not a duality between a dark force and a good one from the beginning. There was a paradise. But things changed later.
My reason for mentioning the local galaxy is the issue of the light on day 1 before the sun on day 3. The tendency in modern times is to try to naturalize all processes, even what happened in the Biblical creation passage, but this clearly does not do. It keeps forcing itself to be treated as a permanent miracle.
The Oxford literary chair C S Lewis did an essay on this fact in GOD IN THE DOCK. "Religion and Science" has the analogy of the regular daily coin being placed in the office drawer. Uniformitarianism can only do mathematics and say that 23 days from now there will be 23 coins more than today. If there is a theft, or a deranged person glued them to the face of the desk shelf or a surplus pile was suddenly found there, we would have no use to speak to the mathematicians anymore; we would need to speak to a detective or a psychiatrist etc. Yet the uniformitarian world expects us to ask it how this world took shape.
Myself, knowing the Grand Canyon, the central Australian theory, and the fossil explosion, I have almost no use for uniformitarianism, compared to catastrophism. However, that takes on events mentioned later in early Genesis, the world deluge, and the dividing of the earth in a tectonic sense. There are many good articles on these things on creationwiki.com.
