Sure, it could. But it comes down to what the story says.
Are you suggesting that God isn’t actually creating anything on day 4? I’m not sure why you’re repeating this.
I’m pointing to terms like bara and asah because those are the words used for “create and make” which define the actions during the 6 days.
He could, but of course the text doesn’t say that.
Remember your previous comment here:
That’s right. Because indeed, “making them” is to define their role. That’s part of the lexical range of the Hebrew terms bara and asah (to make).
In Hebrew, “making” something often is the act of defining its role or purpose.
The verbs bara (“create”) and asah (“make/do”) frequently refer to:
appointing
assigning a function
commissioning
establishing a role
setting something in its proper place
They do not require material manufacturing.
So when the text says God “made” the lights and “set” them in the raqia to rule, to separate, and to mark seasons, that is the act of making.
The “making” is the functional assignment, not a description of physical construction.
Establishing the function is not some afterthought or second event to creation. What you’re observing is in and of itself the creation. And yes God moves things around as well, like moving the water off of the dry land. But the point here is that the earth is already there, as are the sun and the moon.
Your own wording, “God is telling us what they’re for when he makes them”, is exactly how Hebrew creation language works.
