Oops, I just thought you were familiar with 1st Chronicles. Sorry for getting ahead of myself.
The reason I wanted to mention 1 Chron.1:1 was because there the Jewish ancestral list begins/starts with the man Adam.
Luke would have used those long-existing temple records in Luke chapter 3 agreeing going back starting with Adam.
There are many different approaches Jews have to the sacred texts. Some Jews have a very literal interpretation. Some Jews believe there is nothing sacred about the texts at all. I personally have a pretty liberal understanding. Even in sections like Chronicles that I think has a pretty good record of actual history, there are instances such as this genealogy where it relies on other portions of the Bible that are mythological, and not historical.
The story of Adam and Eve is rich and meaningful. It makes pertinent comments on human nature. But it is not a historical account. Thus any "genealogy" that traces back to Adam and Eve is fabricated, inaccurate.
It is not a problem for me. It absolutely does not bother me in any way that some of the things in the sacred texts are fiction. Fiction is perhaps the best way we have to teach values and the deeper truths of life. When I read the Bible, I am far less concerned with "Is this passage historical?" than I am with "What can I learn from this passage? What valuable lessons is it trying to teach me?"
I'm not going to address the two contradictory genealogies in the gospels, both of them fictitious, because, as I said, there is nothing authoritative about the New Testament for me as a Jew.
