Are there any ancient cultures known to...

We can’t find any record of a culture that believed the Sun was the center of the universe, but Copernicus wasn’t the first person to say this. Around 270 B.C., on Samos (an island off the coast of what is now Turkey), Aristarchus put forth a theory of a sun-centered universe, which included his belief that the Moon’s light came from the Sun. He is sometimes referred to as the Copernicus of antiquity.
