Since the earliest times, humans have oriented themselves according to the events in the heavens. Even in the ancient cultures, certain days in the year could be determined with the help of the phases_of_the_Moon or the position of the Sun.
The twelve signs of zodiac are located along the path that the Sun takes, with the background of the stars (ecliptic). One can orient oneself in terms of time and place using a sundial, a sextant and a compass. They were invented in very early times. Many things that determine our daily life depend on the Sun and the Moon.
Day and night, spring, summer, autumn and winter are the result of the rotation of the Earth on the one hand and the path of the Sun on the other. High and low tides are determined by the gravitational pull of the Moon, and also that of the Sun, being exerted on the Earth.
