You’ve looked to far into the abyss it would seem.
No... Consider this. This is not new. These craft have been around in our own linear timeline for thousands of years. They have been documented since the ancient beginnings of both oral and written records including the Bible.
We just refuse to see it. Yet they have never harmed us. There have been by lore a couple battles between themselves, but as bystanders we were never harmed. Still, we do not see.
And even when we do, we use a 12th century superstition to hide what we see because we do not understand it. If you do not understand it then it must be of/or from the devil.
We still say “bless you” when someone sneezes... Why? Do we really and truly still believe this ignorant 12th century superstition of “expelling” of evil demons is why we sneeze?
I am a historian and a theologian, and full well understand the ignorance and fallacy of man and superstition. These are not new. And they have not harmed anyone. And until they do we have no reason to judge as guilty with 12th century ignorance and superstition.
These are us, from the past, present, and future... And it ain’t nothing to sneeze at... Biblically they may be our Angels, but we are too busy condemning them with ancient superstitions to find out.:)
