TBH, I'm probably not the right person to answer that.
I tend to look at it from a broader, extra-Biblical perspective; e.g. what does the sum total of knowledge indicate.
I've spent years looking into young Earth creationism and to me there is just too much in fundamental human knowledge that would have to be flat out incorrect (including physics, cosmology/astronomy, geology, biology/biogeography, and human history/anthropology) to support the notion that the world is only thousands of years old based on a literalistic interpretation of the Biblical text. There are also no independent methods that specifically corroborate the ages of the Earth/universe as suggested by YECs.
Likewise, predating the 19th century there were already notions of a non-literal interpretation of the Bible and Genesis. St. Augustine for example believed that creation was instantaneous as opposed to requiring a literal 6 days. Contemporary young-Earth creationist views are relatively modern phenomenon.
