Who was the first person to discover a rainbow?

Rainbows have been observed since ancient times, and it's difficult to attribute their discovery to a single individual. However, the first scientific explanation of the rainbow phenomenon is credited to the ancient Greek philosopher Aristotle, who discussed it in his work "Meteorology" around 350 BC. Later, in the 17th century, Sir Isaac newton provided a more comprehensive understanding of rainbows through his experiments with prisms, demonstrating the dispersion of light.
