That's more or less my own belief system. I've hypothesized that concepts like God and angels and Heaven and such were likely meant to be metaphorical when they were first conceived, rather than literal - manifestations of certain Jungian archetypes or tropes or however one endeavors to categorize collectively-understood concepts.

I was raised Mormon. The Bible, Book of Mormon, etc. still live in my bookshelf alongside my most treasured books on science and computer programming - partly because of the significance they had on my upbringing and family identity, and partly because one does not have to believe the stories within them literally in order to benefit and learn from them.

In this regard, "holy" scripture is less of a strict historical record (though there are some elements of that as well, embedded within the fanciful depictions thereof) and more of an equivalent to Aesop's fables - stories which were meant to educate, and to convey abstract concepts difficult to succinctly and effectively communicate without such fanciful metaphors.
