After Before Finish
As you can see I new nothing about day and night on my before page because there is a moon and no earth.
On my after page there is a lot more Information that explains how day and night happens. As the earth spins it is day were the sun is shining and night were it is not facing the sun.
Well the earth spins around and the sun reflect on the earth that mean the sun is always on a part of the earth. That means on the other side of the earth is night.
