Earth is spinning on its axis, and we can be thankful that it’s spinning at the right speed for life to exist.
If the Earth turned too slowly, surface temperatures would warm too much during the day and cool too much at night. Under those conditions, plants could not survive the long periods of darkness. If plants didn’t survive, animals and humans could not survive either.
If Earth rotated too fast, the temperature would go through wild extremes. Furthermore, a faster spin rate would create strong and dangerous cyclonic winds because of the Coriolis force. Jupiter spins nearly three times as fast as Earth, and astronomers can observe severe tornado and hurricane-like disturbances on its surface.
Earth’s spin rate is slowing and will continue to do so just as a spinning top slows down. However, there is no need to worry because the slowing is very gradual, lengthening the day by less than two milliseconds in a hundred years.
It’s the rotation of Earth on its axis that gives us day and night. In Genesis 1:14, we read about God moving away the clouds of darkness to reveal the Sun, Moon, and stars, which He had created in verse 1. Genesis 1:2 tells us that darkness covered the planet, and in Job 38:9, God tells us that the darkness was because of a garment of clouds. We need daylight for activities of life and night as a time of rest. Every animal, even insects, needs sleep. To thrive, plants also need a daily period of darkness.
Earth is spinning on its axis, and our day and night cycle is one of the many factors that make Earth the “Goldilocks” place–“just right” for humans to live. The chance of all those factors coming together by accident is beyond the realm of probability. Therefore, we suggest that this planet is not an accident but part of a divine design requiring a Designer.
