Who discovered that the Earth was round? How was this discovered?
That's interesting. Did it take a long time for people to accept the idea that the Earth was round?
Yes, it did. The idea of a flat Earth was deeply ingrained in many cultures and continued to be popular among the general public well into the 19th century. However, by the time of the Enlightenment in the 18th century, most educated people accepted the idea of a round Earth.
