Seriously? The King James is the worst translation. It even bears the name of the guy who commissioned the revamping done for his own political purposes. The best translation meaning the least tweaking for political purposes is the Douay Rheems. Also Even having been made from Adam, was just a clone with the Y chromosomes washed out. There isn't anything more incestuous than that.<quoted text>
To answer your questions,#1, yes, with the King James 1611 probably being the most accurate complete translation.#2, no, it seems like to me that, Adam was an insertion into an already created mix of humans--that he was made specifically for a lineage to produce a Savior and many offspring with the traits of YHWH, Himself, and that Eve was created to help Adam reproduce and train this lineage.
I hope this answers your two questions satisfactorily.
But to the proximate question, that poster may want to read the apocryphal books of the Bible, the stories, histories, and traditions that were in vogue at the time of the Council of Nicea when the Bible was assembled. Some books were not included not because the council thought they were wrong but that they were so popular that they thought that they were so well known that they didn't need to include them (and waste money on transcription of stories everyone already knew)
When you take that into account and read those books, you find that Eve was not the first woman. She was the second. Lilith was the first but she was strong and intelligent and refused to be dominated by Adam and Adam wimped out and went crying to God that he wanted to be the boss and God gave in and made Eve the vapid ditz incestuous clone of Adam. As the stories go, Cain was the son of Lilith and Abel was the son of Eve, so there was a population of people prior to Adam and Lilith but presumably they were the first to be sentient.
