The Western Hemisphere. General term for the Americas following their discovery by Europeans, thus setting them in contradistinction to the Old World of Africa, Europe, and Asia.
If by “First Peoples” you mean any of the tribes around in historical times (post European contact)
I think it is pretty well documented that they did not “write.”
They did carve signposts to indicate trail directions, but that is about it.
If you mean previous cultures, some of whom these tribes overcame, then yes.
There is evidence that there was sometimes some kind of writing of some sort going on.
Whether with an alphabet or pictographic seems to vary with time and place.
If this is “Hopewell “ then it is pre-contact, and yes it is a pretty amazing piece.
If you want to go with the extreme diffusions theories, he could be Chinese.
