How does the Bible then account for the development of the first family of Genesis, into millions of people, without incestuous relationships having occurred?
This one has been bugging me for a while. I brought it up once before in a debate and I was given some answer about Augustine perhaps I'm not sure exactly, but how is the lineage of Adam & Eve explained in the Bible and what does the Bible have to say on the subject of incest?
Any references/examples would be appreciated too, thanks

Incest isnt a problem until the gene pool is narrowed by generations of inbreeding. Incest wasnt forbidden until the law of Moses, many generations down from Noah. Incest wasnt forbidden until that time period. It was common to marry a close relative before then.
For example, Abrams eldest brother died. That brother had two daughters, Saria and Milkah which mean Queen and Princess. Abrams next elder brother married Milkah and Abram married his younger niece Saria. Isaac and Jacob took wives from the family of Abrams brother as well. Some think Saria was his sister because it says she was a daughter of his father but the Hebrew word also applies to a granddaughter.
The Israelites where to marry other Israelites to keep their bloodline pure but close incest of marrying a sister was forbidden by that time to prevent too much close inbreeding. It was still common during the time of Jacob. I dont remember which of Jacobs sons married his half sister Dinah.
Geneitc diversity was much greater in the earlier times and wasnt an issue therefore incest was not forbbidden. Think about it. Adam and Eve carried all the genetic diversity of everyone living today.
Children of Adam and Eve marrying wasnt a sin. It wasnt forbidden and couldnt be at that time. Inbreeding is what sets certain genetic traits as being passed down and what separated mankind into different races. We are all products of a certain amount of inbreeding.
The only reason incest is a sin is because jt is now forbidden by later laws. The sin would be of disobedience.
