The story of the Nephilim is a fascinating one, they were the ‘son’s of God’ which meant they were angels (good or bad?). I’m not sure exactly how this could have happened…but they found the daughters of men fair and procreated with them, this is what the bible says. However, I do know that after this happened people where quite bad enough that God decided to flood the earth.
I’ve always wondered where would they be now? in Heaven or Hell?
As far as I know and have learned, angels themselves do not experience humanity. However fallen angels/demons do mimic humans. This information was revealed by our Lord in 'Direction for our times" and He tells us to be aware as they only want the ruin of our souls. It doesn’t mean God allows any procreation to go on, He wont allow that again.
Well just some more to contemplate…
Thank you for bringing the topic up
