Around 5,000 years ago, the Sumerians, who lived in ancient Mesopotamia (modern-day Iraq), revolutionized how we perceive and measure time. They developed a sophisticated numerical system based on the number 60, known as the sexagesimal system. This unique system led to the division of an hour into 60 minutes and a minute into 60 seconds, concepts that are still in use today. The Sumerians' need for precise timekeeping was driven by their agricultural society. Accurate calendars were essential for planting and harvesting crops. They also needed to coordinate their complex religious ceremonies and administrative activities. To aid their timekeeping, the Sumerians made significant advancements in astronomy. They observed the movements of celestial bodies and used this knowledge to create a lunar calendar with 12 months, which closely aligned with the agricultural seasons. The division of the day into 24 hours, each hour into 60 minutes, and each minute into 60 seconds was a monumenta...

Over 6,000 years ago, a mysterious civilization had detailed maps of our solar system. The Sumerians created these drawings using clay. The surviving drawings show that they understood that the sun is a star at the center of the solar system and that other planets revolve around it.

Additionally, they had symbols related to medicine, which bear significant resemblance to modern medical symbols. To this day, we still cannot understand how thousands of years ago, the oldest civilization of mankind had such profound knowledge of astronomy. This raises the question of whether this ancient civilization was not backward, but rather had advanced far beyond our current understanding of the...
