The question then becomes was this mythos "native" to Earth or did it arrive with the Anunakki and the Igig and the creation of the Dream Time.
In which case it would not be evident in Denisovian culture ... only after the warnings of Stone Grave in the Ukraine!
I could go way out on a limb and wonder if this was the beginning of creating a resevoir of avians on earth to be the carriers of souls awaiting re-incrnation ... a resevoir of Ba holders? And might this have been part of the work of the age and peoples of Oden who slowly moved into the "WEST" . . . ending up on the Isles and Norway, Sweden, Denmark?
Were these folk the VIKINGS?
