Yeah, all of this is absolute horseshit. (Or should I say โbear shit.โ)
Because itโs not referring to living bears in any way, shape, or form. The โbearโ in the Arctic and Antarctic is referring to the constellation Ursa Major or the โGreat Bearโ thatโs visible in the northern sky. Thus, the Greeks in naming something โAntarcticaโ were just saying โopposite of the northโ because the north is what Ursa Major was associated with.
The Greeks had no beliefs either way about which areas were inhabited by bears.
Folk etymology is so stupid and clownish.
