"1. There is one single land mass connecting Europe, Africa and Asia."
Wrong, there are several separate landmasses adjacent. They exist on totally separate continental plates, and the plates move in different directions, at different speeds. This is why mountain ranges such as the Himalayas, the Alps, the Atlas, and others have pushed up, i.e. separate plates pushing against one another. To call this 'one single land mass' is just ignorant.
"2. There is one single land mass connecting North America and South America."
Wrong again. North and South America are on totally separate plates, which move in different directions. They only approached one another within the past few million years. Also, Central America is composed of several plates, with very high tectonic activity.
"3. There is one Australia".
"4. There is one Antartica."
Both of these were once part of other land masses, which split apart eons ago.
"So there indeed is four land masses or corners of the earth."
If Australia counts as a corner, does Greenland?
To equate 'land mass' with 'corner' is a gross misrepresentation of what the author of the verse had in mind.
And how many 'corners' did Earth have when all 'landmasses' were adjacent 250 million years ago, forming the supercontinent, Pangaea?
