Difference between the Norse and Finnish?

Question

Indigenous Nordic faiths typically cater around the old Norse Sagas and Poetic Eddas, with a focus on Odin, whereas the Finnish typically focus on Ukko and the Kalevala of the old Finns. 

To my understanding, Finland is a Nordic nation, so how did these two cultures differ in their beliefs, considering they seemingly were followed in the same region? 

Answer 1

Different languages, different cultures, different names.

Answer 2

While Finland is indeed a Nordic country, it's not a Scandinavian country. The Finns are of a different ethnic stock than Scandinavians, they speak a language that's not related to the Scandinavian languages at all, and their mythology and religion is completely distinct from that of the Norse. 

Answer 3

Different languages, different cultures, different names
