I personally don't think that the story of Adam and Eve is factual. I think it was a story made up by their decendents to explain where they come from. I don't have evidence to support that, but I think it makes sense. My belief is they did not have any stories (or written accounts) of anyone before Adam and Eve, so therefore constructed the story to explain how they got there. It may even have never been intended to be taken seriously, just a fun story to explain where they came from. It seems likely to me that there were many other people around at the time of Adam and Eve as evident by the fact there are others around in the story you have quoted.
Some Christians claim that Adam and Eve had 100s of other children and that those children were the ones people like Cain were talking about. (And one of them was who Abel went to marry... was it Abel? I can't remember). However I find that hard to believe. It sounds like there were many other tribes of people unrelated to Adam and Eve there.
Anyway, the big discussion about where all these other people came from becomes moot when you consider that they were all wiped out by the big flood. Then you have the problem of how the world's population got so big with just Noah and his family being the only survivors!
If you deny Adam and Eve, then you deny the original sin for which Jesus died on the cross. Simply put, you invalidate Christianity.
