Day and night


Why do we have day and night?

We have and night because  of how the earth spins on its axis. The earth takes a whole day, 24 hours to make a complete turn. When one side of the earth faces the sun this part has day the other half of the earth facing away from the sun have night.

The sun is the source of light for day. The sun does not move it seems to move across the sky starting in the east in the morning moving toward the south at noon and then toward the west as the day ends. It is the earth turning that makes it seem as though the sun is moving.

That’s all I can tell you about night and day.
