Thanks zeestephen!
Unless hugely outnumbered, I think the military edge was clearly with the Vikings.
Archeologists need to continue looking farther south. The Vikings weren’t stupid. When they saw the climate was milder and the land richer and more easily tilled the further south they went, they’d have to go for it.
Now, my personal theory (which I will not elaborate on here for fear of abuse from flat-earthers)is based on the fact that the Aztecs god, Quetzalcoatl, was a white, blond man who came from the East to their shores.
I mean, what more proof do you need? Huh? Huh?
