It is true of course that OA had the case endings which were gradually lost. But I
don't understand why languages that lost them are in "a more advanced stage"
as you put it.
Arabic maintains them to this day, though they are dropped in the the colloquial. From this point of view English would be"more advanced" than German.
The traces of case ending preserved in BH such as Chayto Aretz do demonstrate an earlier stage of the language, and thus diachronic development, a subject that came up in another thread.
