To start...are you aware other than the shuffling of the order of the books and the translation to English are there signifcant differences between the Torah and the King James Version of the Old Testament?
The Torah is only one of the three sections of the Tanach, which also includes Neviim/Prophets and Ketuvim/Writings. This forms the acronym TaNaCH. All of these together would more closely parallel the Old Testament. Besides shuffling the order, in some places numbering differs. Also, there are some translations in the KJV which are more theologically informed than informed by a knowledge of the language, usually concerning passages believed to be prophecies concerning Jesus.
Of course, Torah can also be used as a general term that includes Talmud, midrash, the codes, responsas, kabbalah, and the drash I heard the last time I went to shul.
Genesis....Historical Fact, or largely allegory?
It depends who you ask. And to some, it is neither. There is also the question of which part of Genesis we're talking about. The creation narrative is usually not taken literally, with rare exceptions, but other sections of Genesis will be taken as actual history by some Jews.
So it could be history, it could be allegory, or it could be a communal myth whose historical meaning and those meanings it has developed over the centuries are quite distinct.
I think the first question addressed this one. It is unusual to find a Jew who believes in 7 literal days of creation, although some Jews might believe in several periods of time in which creation occurred. Others might even see the entire creation narrative as a mystical text.
Eve being created from Adam's rib?
That's one possible interpretation, but Judaism is a religion of interpretations so there usually isn't just one answer. One possible answer would be to say that when Adam was created, he contained both male and female attributes, and there was only one of him, just as there is only one of God. But Adam saw all of the other creatures with their partners and wanted to be like them. So God made Eve out of his side.
A world wide flood and Noah getting two of everything on the ark?
Again, it's a possible interpretation. Some people accept that there was a historical flood. Some people don't. It's generally rare to find that idea outside of Orthodoxy.
The genaology indicating the world was established in concert with your calendar?
I don't quite understand what you mean.
Copied from my post above yours:
"Jewish beliefs about the afterlife vary quite a bit, are not written in stone. So there are a few possibilities for what might happen to someone after they died if they were not ready to go to gan eden, to heaven. They might be reincarnated and live another lifetime, they might go to a place called gehenna, which is a temporary place (no stay longer than 12 months), and their being there would prepare them to go to gan eden. This might happen by, for instance, them being confronted with all of the wrongs they had done in their lifetime in a way that would temper them so that they would be ready for gan eden. If someone was unable to be transformed in gehenna, then their soul would be extinguished. Odds are, according to this line of thinking, that the individual would not be extinguished, would eventually end up in Gan Eden. Of course, as I said before, these ideas are not written in stone. But these are some of the possibilities that show up in Jewish afterlife theology."
There is no place of eternal suffering.
"Devil?"
No devil. What phyllis said on Ha-Satan. You could also think of this figure as running sting operations for God.
Fallen Anglels, Nephilim?
BB could answer this question better, I think. Afaik there are no fallen angels in Judaism, simply because they have no free will. Even if an angel has a job that to us seems to be "evil", it is still doing a job for God, just one that our subjectivity is offended by. The question of the nephilim is going to yield fairly different responses from different commentators, and I'm not that familiar with what any of them say on this issue, so I'm not going to touch that one.
There is no original sin. The sin in the garden is called a chayt which is the most minor of categories of sin. It is a missing-of-the-mark, like in archery. There are multiple views (I'm sure you saw that coming) as to what the tree of knowledge of good and evil was, what was going on, but the only clear punishments for getting booted out of the garden are those spelled out explicitly in the text, which appear to me to be what naturally happens in a non-utopian reality.
The Christian concept of Original Sin seems to me to facilitate a need for finding salvation in someone else. It removes a person's power to do it through their own work, which is what Judaism has the possibility for.
Hope that helps.
