The incest issue is actually an artifact of the religion initially not being monotheistic. Each region had their own religion and they were all treated as equally valid (at least by early Jewdaism), so the creation story was basically “God created a paradise (and everything else) and two people in that paradise, but then they got kicked out and had to go live with all the other people made by all the other gods”. Adam and Eve had Cain and Abel, Cain killed Abel, so it was pretty much just Cain that carried on that legacy.
Then, eventually they went monotheistic but didn’t/couldn’t resolve the issues that introduced with the earlier stories (Noah’s story also has similar issues, though I’m not sure it also once had a resolution of “other gods made more people” or if the resolution involved smacking anyone who brought up the question).
The solution to naoh’s story is also semi “incest” btw. I recently wondered the same a quick google told me naoh was on the arc with the wives of his sons. Not his sons, their wives. They repopulated the world…

This. Iirc, after the murder incident, Cain goes abroad and marries a woman from a different land (?)
Alternatively her kidnaps his sister, or marries Lilith
