How does day and night occur?

Day and night occurs because the Earth revolves around the Sun, and when the Earth revolves, different parts of the Earth get sunlight at different times. When it is night in one place, it is daylight in the other. This is because we only have one Sun and wherever the Sun is, that is where it will be bright.
