Yes, these myths are still taught to school children. It makes a good story, the dumb ol' people of hundreds of years ago who thought Earth was flat. Kids love stories of stupid grownups so it keeps their attention.
As a child, I heard stories of people warning Columbus that his ships would fall off the edge of the Earth. In fact, as I learned as an adult, he was told by astronomers of the day that his voyage would take longer than he realized because they had estimated the size of Earth with considerable accuracy. Some of them told him that a space that large was unlikely to be empty, so he would likely find previously uncharted land masses as he tried to sail to India from western Europe.
For those Darwinists who did not pay attention to their world history class, Columbus did find the predicted land masses, which were the Americas. Because he did not accept the advice of the intelligent astronomers, he believed that he had proved them wrong by landing in India much sooner than they predicted he would. He called the people he met "Indians," due to this error.
True story, bruh . . .
