I'm not invested in this book, but I am interested in the idea of monotheistic religions like Judaism and Christianity having these incongruous elements I associate with their polytheistic cultural roots. You can bet I didn't learn about the nephilim in religious school.

I had to google for Rashi's commentary because my books are buried right now--Rashi is not a fan of the nephilim. He follows other commentators who translate "benei elohim" as "sons of princes and judges." Goodness.
