The sun circle around the earth. In and out throughout the year. The north is at the center of the circle the sun makes on a daily basis. The further south the sun makes its circle around the earth, the further away it is. The further away the sun is from you, the lower the sun will appear in the horizon. During winter, the sun circle around the earth at its most southern point, hence why it is cold during winter, the sun is further away from us, less light reaches us.
The sun is moving, which is the source of sunlight. During a sunset, you can watch the sky go from blue to purple, then to black as no more visible light is reaching us, as the angular diameter from us to the sun is to small, and only ultraviolet light is able to reach us. The smaller the angular diameter is between us and the sun, the lower the frequency of light reaching us will be.
So if I can still see the sun from up North when it's all the way in the south, how do days and night work? In winter the sun during the day would be further away than it is during the night in the summer so why can't I see the sun during night hours?
Because the sun moves in a circle. If you stand on the North Pole, which is the most northern point on earth, and the center of the circle the sun makes, you would not experience a night or day cycle during a 24 hour period. But as you move south, there is a distance between you and the center of the path the sun makes, which means that that the distance between you and the sun changes throughout the day.

Sure but why does that mean I don't see the sun at night?

Except the angular diameter of an object can never become negative, so try the fuck again.
The wavelength that reaches us can become so small that it no longer is in the visible spectrum of light.
That only happens when the source is moving and only at speeds that are OBSERVABLY IMPOSSIBLE for it to be moving.

Because the sun is further away from you at night, then it is at day (assuming you are not at the North Pole).
