The Magellan expedition circumvented the Earth in the early 1500's, proving the world is a giant ball.
While it did not exactly move in a straight line in one direction (the ships needs to make port, time to time.), it was a astronomical achievement for its time.
Sail straight west, without veering and eventually you will end up where you started. This is not possible on a flat plane.

Circumnavigated, and yes, it wasn't a straight line, but because continents were in the way
False. you will always have to adjust north to go around and end up where you started. if you didn't you will be heading south.
