I really love your analysis and I understand where you are coming from. That being said, I wish I had the time and the knowhow to explain how symbolic patterns are universal. The only other suggestion I have is to check out Matthieu Pageau's book The Language of Creation. If you don't feel up to purchasing it or reading the whole thing, the breif sample Amazon provides is a great way to understand universal Symbolism, as it gives a more detailed expression of how the cosmos works.
If you want to read more about this stuff, you can check out Pageau's brother's book, The Language of Creation: Cosmic symbolism in Genesis. I found it very helpful, though it would have been nice if Mattieu could have told us where some of it came form (Iraneus, and other church fathers, I belive).
“Through New Eyes: Developing a Biblical View of the World” by James B Jordan is another title I've heard recommended as regards symbolism, though I haven't read it myself.
