The name "Iran" means "Aryan." That means that the ancient Persians (ancestors of the Iranians) were descended--at least in part--from Aryans who had moved westward out of India (originally). The Aryans were the gurus of very ancient (Vedic) India, originating in southern India (Dravidic). That--in a nutshell--is the truth about the Aryans; there were northern people called "Aryans," who invaded India somewhere around the 3000's BC (before 1500 BC). Thus the modern Caucasians of today are "Indo-Europeans" who are descended from a mythic Aryan people originating somewhere in eastern Turkey.
It's true that a people originated in eastern Turkey--after Noah's flood circa 5,500 BC. These were the children of Noah's three sons: Shem, Ham, and Japheth. "1And the whole earth was of one language, and of one speech. 2And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there," it says in Genesis 11. So there is a remnant of truth in the false Aryan origin/invasion theory.
Moving on to angels, it is said by Michael Hur (shieldoftheson on Youtube) that the Cherubim are the highest rank of angels. This I know to be true. Hur says that a cherub reflects--to the greatest degree--God's greatness and majesty. Cherubim have the appearance of beasts, who can shape-shift. They can appear as dragons--supposed to be where dragon imagery from ancient times originated. Cherubim can also appear as creatures with the bodies of lions and with the heads of eagles--sounds like the gryphons of myth. Of course Satan "art the anointed cherub that covereth" (Ezekiel 28:14). These are spirit bodies that the angels have, as opposed to our earthly bodies.
According to Hur, a cherub can turn himself into a metallic appearing UFO or flying vehicle. In essence they can shape-shift into a variety of things. A cherub can fly without beating their wings. This kind of angel can soar for ages. Psalm 18:10 says, "And he rode upon a cherub, and did fly: yea, he did fly upon the wings of the wind."
Immediately below the cherubim in rank are the Seraphim. I've read that the Seraphim are serpentine in appearance. I've also read that the Seraphim are shining creatures of light. It is said that most--if not all--of the rebel angels (a third of the host) are of the Seraphim class. And the elohim (Anunnaki of the Seraphim kind) "which kept not their first estate, but left their own habitation" to take wives from among the daughters of the Sethites (Jude 6). This was a group of angels--some 200 of them (according to the Book of Enoch) not part of the original rebellion--who decided to transgress the natural laws that God had laid down. (The Book of Enoch has the names of some of the transgressing group of elohim who came down to earth. We are told this in Exodus 23:13 concerning their names: "And in all things that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.") So Satan took advantage of this wicked act by these particular Seraphim--to further his agenda: the corruption of man's DNA.
Seraphim can also shape-shift, like their more powerful Cherubim brethren. Like the latter, the former can also transform into flying metallic ships. (Now the holy Cherubim and Seraphim do not use their shape-shifting ability to deceive--as the satanic angels do--meaning that the good angels will appear to men and women as God directs them to.) Perhaps they can turn into large, metal birds too?
By the way, I've become suspicious of Michael Hur. He asks for money on Youtube. More like he begs for money. Christians should be wary of Bible teachers who make an appeal for money.
