Oh that was centuries ago. In the US, we’ve even divided states in a similar manner over the years. The Province of Carolina became North Carolina and South Carolina. Dakota Territory -> North and South Dakota. Virginia and… West Virginia (not sure why no “East Virginia”).

I suppose you can say it’s “wrong” on the Internet, but if you tried the six-continent model on a school test in an English-speaking country, it would be marked as incorrect.

There are also five- and I think even four- continent models I’m some cultures. The thought of any of them being “wrong” is really interesting, to me. Personally, I’ve never really thought about any of them as “right” or “wrong”, just cultural differences.
