I know SPAL/JC have left the building, but I couldn't let this pass (it's one of my pet peeves and it amazes me how common this misunderstanding is).
That's why MOST ancient cultures asserted that the Earth was resting on a giant turtle......or that Atlas was carrying it......
In Greek myth Atlas did
NOT carry the Earth. There are several different variations to the story but basically he was a Titan who carried the
sky as a punishment from Zeus who was shown the severed head of Medusa by Perseus and turned to stone.
Classical Greek statues of Atlas show him holding a globe on his shoulders but it is a celestial globe showing the constellations, not the Earth.
I'm not 100% certain of this but I believe that when Mercator published his collection of maps the cover had a picture of Atlas on the cover carrying the Earth, rather than the heavens, which is where the misunderstanding comes from (and why we use the word Atlas for a book of maps).
