The idea of Truth in this context has been corrupted by a form of so-called “literalism” accompanied by rhetoric pushing the believer to accept an interpretation at odds with truth in the name of “biblical inerrancy” which takes certain words literally and not others.
And then on the other side one finds no shortage of those pushing biblical “errancy”.
I will ignore the latter.
In regards to Noah, I just explained this to my wife the other day as she had the same question.
So let’s get right to it. We are not bound to interpret terms like “the whole earth” to mean the globe. But rather all the earth that Noah was aware of. Noah wrote the book, or his sons did. How was he to know if mount Everest was underwater?
And more importantly why would you define the “whole earth” as “the Globe” if no one was living on mount Everest at the time.
The important detail is that the humans of the day were nearly wiped out, along with their livestock (which they had been working so hard to domesticate)
Importantly genetics has shown that at one point the human population which had been formerly larger was reduced to around 50 people.
This coupled with the prevalence of flood myths in essentially all cultures gives a strong case that what was described in the Bible is true.
Noah had no conception of a Globe. You must consider that if he looked around and saw no land then he would consider that the entire world was flooded.
And for all human intents and purposes, it was. All who didn’t enter the ark were washed away.
Why should this not be considered a “literal” reading?
It is merely rhetoric that demands words be understood to mean what they mean in a modern science-based context.
Even numbers need to be considered not only as literal numbers but as words having a literal meaning in the ancient understanding.
For this example, 40 days is a symbolic number that means “a time of testing”. Trying to apply our modern scientific precision of 40 days = the entire globe was covered in water for 3456000 seconds is so badly conceived as to be deliberately factitious, for if it was but one second more or less one might claim the Bible to be inaccurate.
Yet the Bible is recording a near extinction event in our human past that was only myth to be taken on faith until genetics now suggests that it indeed happened.
We don’t really know many details with certianty, but we can be patient and study the past and have faith the Bible will be vindicated in the end.
