Sorry for the late reply, I just woke up. I believe that the disembodied spirits of the nephalim that were destroyed in the flood are left over. A body is just a biological machine. I personally didn't feel any fear or demonic forces, just confusion. I do believe your statement however. How do you convince a whole population that God as we know him is not real? Even the Vatican says we cannot limit the creative power of God. It would fool even the Elect if it were possible.
