You actually see the phases of the Moon the same way during both day and night, it's just that the brightness of the sky makes it harder to see the Moon during the day.

Here's why:

* The Moon's phases are caused by its position relative to the Sun and Earth. As the Moon orbits the Earth, the angle at which we see the sunlit portion of the Moon changes, resulting in the different phases we observe.

* During the day, the Sun's brightness overwhelms the Moon's light. The sunlight scattered in the atmosphere makes the sky very bright, making it difficult to see the Moon, especially during the day when it's not very full.

* At night, the absence of sunlight allows us to see the Moon more clearly. The sky is much darker, allowing the Moon's reflected sunlight to stand out.

So, the Moon's phases don't change depending on the time of day. The only thing that changes is our ability to see them due to the brightness of the sky.

Here's an analogy: Imagine you're trying to see a small candle flame in a brightly lit room. It's difficult to see the flame because of the room's brightness. However, if you turn off the lights, the candle flame becomes much easier to see. The Moon is like the candle flame, and the Sun is like the room's lights.
