Another cradle of ancient world civilization is the Euphrates River and Tigris River basins in West Asia. Before 3000 BC, the nomadic Chaldeans came to the two river basins and established a country in today's Iraq. They believe in astrology. Long-term astrological observation. The Chaldeans found that the stars in the sky changed with the seasons, and they used them to predict good or bad luck. In order to meet the needs of astrology, the Chaldeans paid special attention to the dynamics of several bright planets. They connected the bright stars in the starry sky with imaginary dotted lines, depicting the images of various animals and people, and formed the earliest 12 constellations, including Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Later, it became the famous zodiac. This is the origin of modern constellations.

Around 540 BC, the Chaldeans conquered the Babylonians, and they completely accepted the advanced culture of the Babylonians. Besides the zodiac, Babylonians also created other constellations. This knowledge was introduced into Greece.
