If you are saying that we read the historical narratives in the Bible as history, then I would agree. But not all the Bible is meant to be taken literally, e.g., the Psalms are a book of poetry with poetic imagery. The prophets and Revelation are apocalyptic literature, again, with many symbols and images, that, while literally true, are not necessarily to be read literally.
The problem is when we try to read history as symbolism or allegory or prophecy as history written in advance as we would read the morning newspaper.
I take Genesis 1-3 as historical narrative so I believe the Bible teaches that the universe was created in 6 normal days, 6 evening-mornings.
Yes. the problem seems to be a slippery slope. If one says Gen 1 is a myth, I think the slop leads to saying the entire Bible is a myth
