about 1 month ago

The night comes after the day and it is mysterious. In fact, some people worship it. There is even a saying in Yoruba which goes "A child born from a good home doesn't walk outside at night" because it is believed that the night is for predators both animals and humans who intend to feast on innocent preys. While the night offers protection, it still wakes our primeval fears.

The back and forth of the Night and the Day is almost a 12 hour thing where they both share almost the same time to own their space and this back and forth never ending cycle has been influencing the day-night rhythm of all living beings for millions of years. At night, before artificial light was discovered, the stars and the moon played an important role of lighting and the stars were used to navigate before we developed modern compasses and maps.

In the past, people owned moon almanac as it was important for knowing the movement of the moon, and how it was cycling. This was important for travel as well as entertainment because people had to understand. The moon plays a lot of role in keeping our earth, without the moon, we will not have a 24 hour rotation, it would be about eight hours and this is because the gravitational pull between the earth and its moon slows the earth's rotation.

Asides from the tropics and the equator, there are four seasons everywhere else on the planet earth and this is because the earth's axis is tilted 23.4 degrees. The tilt causes the sun to hit the earth at different angles and this angles determine if the days will be shorter or longer. In all, the seasons of the earth which includes the rise and set of the sun is determined by the rotation of the earth around the sun.

When the sun goes down in the west, a grayish blue arc known as the earth's shadow is seen in the east. Soon darkness covers everywhere and night begins and when the moon is out, and so are nocturnal animals. This animals have adapted to living and performing their activities at night like bats that uses echolocation to navigate through darkness, hedgehog are able to go around thanks to their good sense of smell, and so do other animals that walk at night possesses one ability or the other.

Because we are not able to see well at night, we humans need artificial light to be able to navigate around and we make the illumination similar to that of daytime. Day and night influences our cycle as living beings which includes wake time and sleep time. Every living things needs to sleep, some animals like the dolphin, or shark sleep with one hemisphere of their brain at a time. Sleep is as important as eating or drinking and we should take care of it properly.

We are known to fear the night, and the night itself isn't making it any easier with a lot of event happening in it which includes the movement of nocturnal animals, but its not only this. When there is thunder storm in the day, it is often different from thunderstorm at night and this is because warm humid air allowing thunderstorm to fall more easily. In all, the night is still very important for our survival as humans and the existence of our planet.
