lol, are you serious??? Of course we know what the dome really was,
you look up at the sky, and you see a big blue dome

.
You see rain pouring down from the big blue dome,
and you assume there must be a vat of water hovering above the dome,
that god pokes holes in from time to time to produce rain.
Well for the untrained eye, it sure looks like it.
Well, perhaps Noah never did see rain until the flood, but Moses sure did.
As I've said, the
writers of bible are limited to understanding things relative to their time,
not relative to the time of their characters, they wrote about, or relative to our time.
But since you mentioned the Flood,
let's not forget that most of the themes (angry god, chosen survivors) of Genesis flood,
where around for a couple centuries before Moses penned his version of events.
You can try and deny it all you want,
you can even present elaborate theories to suggest that science of the bible is accurate,
but what you forget is that in doing so, the only person you are convincing is your self.
Because there no lessons in science that the bible is capable of teaching us.
In the same vain, there is no cohesive bible,
unless you are well aware of the anthropological influences that shape it.
No one stoned the adulterer because god willed it,
they stoned the adulterer because they willed it, and then wrote god sanctioned their will.
These individuals had no understanding of future, or evolving morality,
just like they had no understanding of modern science. These writers, wrote their books,
with the audience of their time, in mind, not us.
Paul particularly, he's writing confronting issues in Churches during his time.
Paul was concerned with issues facing his time, he is not aware, nor is he confronting moral issues of our time.
Christ is the only figure that teaches in future and current tense,
and that's why he places special value on the gospels, compared to other books.
And as intricatic, so nicely pointed out, you can't use
your culture to understand the text,
you have to peer through the eyes of the culture the authors were living in.
But this "putting yourself in past shoes" understanding, is not limited to just a few portions of the OT,
you have to keep these shoes on for the reading of the entire bible.
The writers of the bible are not writing of Today's homosexuality as sinful,
they are writing of there day's "Homosexuality" as sinful.
None of these Biblical writers explored the questions that have arisen today,
when we see a homosexuality beyond the sexual act,
that did not exist (or was not known about) in the times of the authors.
Our understanding is much different, than their understanding,
we live in a time, when we can see homosexual couples beyond the sexual act,
who are capable of a loving, committed, relationships just as their heterosexual counterparts.
Perhaps it's time we allow them to live in peace.
