There are two days out of the whole year when day and night are just about the same length: 12 hours. These days are called equinoxes because the direct sunlight rays move toward the equator, making the sunlight about equal in both the Northern and Southern Hemispheres. The Fall (autumnal) equinox for the Northern Hemisphere is September 21 or 22, and the Spring Equinox is March 20. In the Southern Hemisphere, the names are reversed for the two days.
Because of the apparent width of the solar disc, the days at the equinoxes are still slightly longer than the night. The parity of day and night occurs the day before the vernal equinox, and the day after the autumnal equinox.

What would happen to both night and day if the earth took twice as long to spin on its axis?
Days and nights would be twice as long, obviously. The slower rotation would have impacts on the weather, much of which is driven by the Earth spinning. Days would be warmer and nights cooler, for example, because each spot on the Earth would have twice as long in the sunshine to heat up, with twice as long at night for heat to radiate away.
Why do we have alternate days and nights?
The world alternates between the morning and the night because the Earth is constantly rotating around the sun. When this happens, the part where you are on Earth will eventually be pointing away from the sun. Thus creating morning and night alternations.
Was the world really created in 7 days?
As most of the traditions narrate, according to the heavenly religions, the world (7 Skies and the earth) was created in 6 days and the 7th day was meant for rest.

Many of the religious Figures are symbolic. Day may be equal to 1000 normal earth days, or may be equal t0 50,000 days each. Our Creator could have created everything within a twinkling of an eye, but he created it in 6 Days.
