No, you didn't. I did.
However, you did explain the argument about what is meant by "firmament" as the sky being described in "all kinds of colorful ways."
Not exactly. His reference was to Genesis 7:11 where it says that "the fountains of the great deep were broken up and the windows of heaven were opened"
That means it rained really hard but deco wanted to fucus on his assertion that firmament must necessarily mean solid and the windows must necessarily be literal "windows. And since the sky isn't solid and has no windows that the whole thing never happened.
I am simply putting forth the not-so-far-reaching argument that most things in the bible are described in "all kinds of colorful ways." If you apply the "colorful ways" argument to entire stories rather than individual words, we will be much closer in our viewpoints than you think.
I'm not sure my "colorful ways" argument was meant to be what you're taking it as. It was my way of saying that I think he was nit-picking and being silly about it. If you told me that "it rained cats and dogs", I would assume that it rained hard. I would not concluding that the whole thing must be a fabrication because we all know that it never rains cats and dogs.
