The idea of a flat Earth was a common belief among ancient civilizations, but it was disproved by scientific observation and reasoning long before the rise of modern astronomy.
Here's why:
* Ancient Greek philosophers like Pythagoras and Aristotle already had strong evidence for a spherical Earth, based on observations like the changing position of stars and the curved shadow cast by the Earth on the Moon during a lunar eclipse.
* Eratosthenes (around 240 BC) even calculated the circumference of the Earth with surprising accuracy.
* Medieval astronomers built upon this knowledge and continued to refine our understanding of the Earth's shape.
The idea of a flat Earth resurfaced in the 19th century as a fringe belief, but it has no basis in scientific fact or any legitimate scientific theory.
