Ancient people saw the stars every night - and they could see a WHOLE LOT MORE than we can now. It was amazing, awe-inspiring, beautiful and terrifying all at once. They navigated the sky by finding patterns in the stars. They called these patterns constellations. These were not only legends and myths of gods, godesses, kings and queens, but also monsters and heroes that paraded through the night. The constellations were used as a tool to help people survive - by watching the sky every night, ancient people could tell when to harvest and when to plant - when the rains were coming and when it would be dry, when animals would migrate and when they would hibernate. With all of the light pollution of today - the sky today looks very different to the way it did back then.

Because they did - and still do. The Sun is a celestial object and it provides light and warmth - without it, all life on Earth would perish. Without the moon, life on Earth would cease to exist, too. The stars make up patterns called constellations. These constellations were used as a tool for ancient people to survive. By using the constellations, the ancients knew when to harvest and when to plant, when the rains were coming and when it would be dry.
Our ancestors noticed the stars, watched them every night, and observed how they changed over the months and season. Some of the stars seemed to resemble patterns, gods, myths and legends. Our ancestors began to tell stories about those gods in the sky. The constellations of the zodiac acted as a makeshift "calendar" for our ancestors. By watching the constellations, our ancestors knew when to plant their crops and when to harvest them. They could tell when the rains were coming and when it would be dry. The skies gave them a tool that helped them survive.

They are fascinating. Our ancestors used constellations to determine when to hunt, when to plant, when to harvest, when the rains were coming, when it would be dry - the skies gave them a tool that helped them survive.
Celestial constellations have religious and cultural significance. They also can be used as navigational tools by orientating star maps at certain times of night to match up. Many uses.
