you no doubt use hermeneutic principles such as historical usage in your determination?to be suggesting a reliance upon an historical-critical hermeneutic on my part.
Of course I agree that "historical context is a key for interpretation of any text." If you are going to consider history, you should then consider historical interpretations of the text. And, as I indicated above, there have been sages even in ancient times who interpreted Genesis 1 figuratively. IIRC, there is even a passage in the Zohar where the age of creation is given as around 15 billion years.
There is no reason not to take it literally as it is a historical account
You are assuming that it is an historical account.
In its most natural sense, it is. Only through distortion does it become otherwise. As a Christian, I see Jesus looking at it LITERALLY. As a Jew, you should see the same as it portrays itself as such. Who is God, YHWH or Science?
