Holding bible history as true still would give us no reason to think the universe is so young. We tend to focus so much on the physical and material process of creation with that we don’t tend to consider whether the Israelites would have cared about that much, and really why the revelation given to them should be expected to address it. Some clues in the text like the word “bara” connoting the bringing of order and function (as in “create in me a clean heart”) and the purpose of the sun and moon (signs and seasons) being prioritized over their names implies the text of Genesis 1 isn’t the construction of a building, but the furnishing of a home or temple, where God can commune with His human creation. https://www.youtube.com/watch?v=R24WZ4Hvytc
