All of North America was once
supercontinent of
Laurasia, along with most of Europe and Asia.
The other supercontinent was called Gondwana, which would later become basically every other continent.
Recently I was looking down the list of the continents that once were…
So I was thinking… suppose there were civilizations then. Would they get into a giant arms race? There were only two giant land masses. Maybe later in their development their peoples wouldn’t even know about each other, just as Europe didn’t know about African civilization or the vast Chinese or Indian empires.
