Winter and Summer depends on the tilt of Earth's axis towards sun

Seasons and constellation seen in different times of year is related to the tilt of the earth as it orbits around the sun in 365 days. Earth spins on an axis that is offset by 24 degrees. During summer, the axis is tilted towards the sun. So it gets more sunlight and we get our summer season. But more importantly we get a particular view of the sky.

In winter, axis is tilted away from sun and we get winter season. Now we get a different view of the sky.

Our ancestors also noticed these changes that enables them predict seasonal changes and help them to adapt.
