Ursa Major is a very common constellation. It's identified in many way by many cultures: it's also common it identify it as a plow, cart, or wagon. To me it's just the Big Dipper. This is sort of like the birthday problem in statistics: It's overwhelmingly unlikely that two specific cultures would at random choose precisely the same identification. But it's extremely likely that of all cultures, there are two would choose the same identification. Real evidence of cultural contact between Ancient Greece and the Ojibwe would be a major breakthrough. But this is just random similarities.
