Did People use to believe that the Western Hemisphere was all ocean?

by Cranyx

So I know that the idea that people use to believe was flat is an annoying myth, but what did people think was there? Did they just have no clue and didn't want to risk finding out?

This is a general question so if you know info about Asia or Europe, I'd like to know.

I'm sure people in the Western Hemisphere certainly didn't believe they were all ocean. I assume you are asking from a European perspective. Vikings had settlements in the Western Hemisphere by circa 1000. Here is a debatable map depicting North America before Columbus arrived. The authenticity of this map is questioned. Are you referring to scholars or the general public views of the Western Hemisphere?
