If you asked a Maori how old is their nation they certainly would not be saying when the white man arrived. It is all interpretation and my view is my city is my nation because it was a very ancient key river crossing and is to me identified in its own right. Back before many tribes merged it was the river crossing. Yep, I am pushing the boundaries but that’s because like you this concept of country I find a bit forced. @adcarrymaokai does the above answer your question? It is interpretive, includes how you feel and is a bit of fun. But also I have found some great informative posts.
