It’s Germanic paganism not Norse paganism
It would be more accurate to call it Germanic paganism instead of Norse paganism since it was practiced not just by the Norse, but by all Germanic peoples since ancient times. The only reason it's called Norse paganism instead of Germanic paganism is because most of our information on it comes from the Norse who were the last holdout of it by the 8th century AD. The other Germanic peoples in antiquity and even in the early middle ages worshiped the same gods, just referred to them by slightly different names because of how different languages work. For example, the name of the god "Odin" (Old Norse: Óðinn) is just the Old Norse name for him. His name was rendered in Old English as Wōden and Old High German as Wōdan or Wōtan. They all derive from the Proto-Germanic name reconstructed as *Wōdanaz. Similarly, the name of the God "Thor" (Old Norse: Þórr) is just the Old Norse name for him. His name was rendered in Old English as Þunor and Old High German as Donar. They all derive from the Proto-Germanic name reconstructed as *Þunraz.
