I am convinced that during the days of Jared there was an initial group of about two hundred angels who desended into the reigon around Mt Hermon and married human women. Then there was a trickle down of angels up until the flood. After that (the flood) there was a continual trickle down until approximately 1300-800 B.C. My assumption is that by then, those that couldn’t resist the allure of women were just about all here on the earth. I suspect that there are still possibly an occasional angel that falls in love and decides “it’s worth it”.
