I have prayed long and hard about this for the Lord to open my eyes about what was written. Forget what you think you know. Understand this: elohim that was translated God in the OT actually means devine beings (plural) or heavenly beings. Now when it states in Gen 1:26, “God said, let us make man in our image and after our likeness.” It states in fact, the gods said let us make man in our image and after our likeness. Now, some devine beings are humanoid. That is what it states. That is why it also states, the sons of the gods saw that the daughters of men were fair (beautiful) and took them as wives. I’m not adding to scripture. That is a direct translation. It is only assumed that extra terrestrial beings (heavenly beings, elohim) are spirit. They aren’t shapeshifters.
and when these believers married unbelievers, some angels did something which required that God restrain them in chains under darkness ... but we don't know what these angels did ???
