If the Nephilim died at the flood, did they have a "spiritual" existence? If this was plasuible, could it be that they "miss their physical bodies" and that is why they seek to possess people to have their old life back?
When I was one of Jehovah's Witnesses, I was indeed fascinated by the subject of the Nephilim. I asked many questions but few were answered; however, I was told by the Witnesses that when the flood wiped out humanity, the Nephilim abandoned their fleshly bodies which were destroyed at the flood and they resumed to their spirit existence in the heavans. And yes, because they miss their earthly existence they possess people in an attempt to relive the experience because their powers of materializing as humans was taken away by Jehovah. (their powers having been taken away, was referred to as being in Tartarus, a debased condition).
I always wondered how this entire phenomenum could occur since humans and spirits were two different species; could it be something like Christ's existence since he was the product of a spirit (Jehovah) and Mary (human)?
By now I have become thoroughly confused.
