Interesting article, which I mainly agree with. I wholeheartedly believe the Nephilim in the Bible are the Jinn in the Quran. The relationship is much clearer than you might think.

There are many misconceptions in the Islamic literature, nowhere to be found in the Quran, despite many clues from the Hadith. The Jinn simply means "The Fallen Ones", which makes perfect sense in the Quranic text.

“And (remember) when We said to the angels: “Prostrate yourselves unto Adam.” So they prostrated themselves except Iblis (Satan). He was one of the FALLEN ONES (jinn); he disobeyed the command of his Lord....." [18:50]

This fundamental misunderstanding caused the fabrication of many human made facts and concepts, none of which has any bearing on the Quran... Some include...

1. that the Jinn are spiritual and/or invisible beings (openly contradict the Quran).

2. whether Iblis is a Jinn or an Angel (Quran says he is both, a Fallen and an angel, a FALLEN ANGEL)

3. that the Angels have no free will (openly contradicts the above example, where an angel was able to fall from grace, by using free will, along with his followers and progeny!). Nowhere in Quran, it says Angels have no free will. On the contrary, Quran states that the Angels FEAR God, and worship only him because of their FEAR. A robot with no free will has no reason to fall or fear.

4. that Jinn are spiritual beings. Openly contradicts Quran which says they are mortal beings, living in tribes, often mixing with humans, subject to a human messenger, having men from them, with eyes, hearth, ears, and noses etc... Likewise, at least on earth, all angels are also depicted like humans, appearing physically so. There are no spirits in Quran's earth.
