Ok I'm ending this. First off Death Long before God made Angel and Man he made the first beasts. Angel is used as the same as man the collectively of the group until prove different. Also if you use Death's statement about the Darkness war as evidence that Archangel's predate them. I can use the logic that he didn't state them as they weren't used in that war according to it. Now as Castiel said Levianthans can kill Angels, that is evidence. Yes the Archangels are far more powerful, but regardless they still are angels first. As evidence has more support that Levithans can kill Angels and negate their powers. We will list Leviathans as a Possible Weakness. As even in the uncertainty of the canon info, there has never been any evidence as of now that has shown or stated that contradicts that Leviathans can kill Angels.

And if you use Godstiel he was stronger than Michael, and while he had all the Leviathans inside of him. He had 30 million plus souls too. And Castiel didn't considered himself an angel at that time. Even Death while calling him an angel, he called him a mutated one.
