If this religious document was from God I would expect it not to contradict modern scientific theory.
this is the fundamental call of the inerrancy movement since the early 20thC.
God is truth.
The Scripture is from God.
therefore where the Bible talks about science it is truthful.
The problem is context. Modern science does not form the context for Gen 1, ANE culture does. Gen 1 is not addressed to us, it is addressed to the ancient readers of the text, we are essentially shoulder surfing, peering over their shoulders at them reading the text. As much as possible requires us to put ourselves in their sandals and read it as did they.
Now, if you have some sort of textual evidence that Genesis 1 was merely meant to be a metaphor then by all means please present it.
the wedge into Gen 1 as history and science has been well known for more than 2 millennium, the light is created before the lightbearers. There are excellent books on the topic.

post-edit
the topic of the Sabbath week forming the metaphor for Creation in Gen 1 has often been discussed in the Christian only origins forum
see:

for a good example.
merely meant
it is curious to me how words not only bias discussions but betray controlling ideas.
do you really think that God presenting Creation as if He were the Great Workman building the universe as His temple in the motif of a Sabbath week deserves the modifier "merely"?
why is something devoid of scientific principles so much less truthful than literary truth?
why is it to modern scientism thinking people that only science presents true truth? if the order of Gen 1 is not historical and scientific than it is merely literature and therefore demoted to something less than truthful?
again YECism betrays it's modern roots in 19thC scientism.
