It appears illuminated to us because we see the reflection of the Sun's light upon it. Some of it bounces back to Earth and to your eye, sensing the light. Only the portion of the moon that is lit by the Sun during a given moon phase will show as illuminated, giving us the images of the half moon, full moon and so on.
The moon is illuminated because it reflects light from the Sun. This phenomenon is visible to us on Earth depending on the position of the moon in relation to the Sun and the Earth. Different phases of the moon result from how much of the illuminated side we can see from Earth.
The side of the moon that is illuminated is always the side that is facing the sun. Whether you perceive that as facing east or west depends on the phase of the moon and the time of day that you observe it. If the moon is in its first quarter and you observe it in the evening, the side that faces west (toward the setting sun) is illuminated. If the moon is in its third quarter and you observe it in the morning, the side that faces east (toward the rising sun) is illuminated.
The Moon appears different every night due to its changing position in relation to the Sun and Earth. This causes different portions of the Moon to be illuminated by sunlight, creating its phases. The Moon's orbit around the Earth also affects how much of its illuminated side is visible to us.
During a new moon, the moon is positioned between the Earth and the Sun, making it largely invisible from Earth. This occurs because the side of the moon that is illuminated by the Sun is facing away from us. As a result, we see no illuminated part of the moon during this phase.
The moon is not a luminous object; it does not generate its own light. The moon is visible to us on Earth because it reflects sunlight. The amount of light reflected depends on the moon's position in its orbit.

The moon is still there it just appears as it is gone because the portion of it that is illuminated by the sun is facing away from us.

At the time of answering this question, the moon is waning (waning gibbous), which means we will see less of the illuminated side of the moon.
To determine if a crescent moon is waxing or waning, look at the shape of the illuminated side. If the illuminated side is on the right, it is waxing (getting bigger). If the illuminated side is on the left, it is waning (getting smaller).
The moon was in its waxing crescent phase, appearing 33% illuminated at 6 PM UTC.
The new moon phase appears darkest to us because it is positioned between the Earth and the Sun, with its illuminated side facing away from Earth. This means the side of the moon we see is not illuminated by the Sun, making it appear completely dark from Earth.
The Moon appears different every night due to its changing position in relation to the Sun and Earth. This causes different portions of the Moon to be illuminated by sunlight, creating its phases. The Moon's orbit around the Earth also affects how much of its illuminated side is visible to us.
The whole moon is there, but we only see the parts illuminated by the sun. We don't normally see the parts of the moon that are in deep shadow.
During a new moon, the moon is positioned between the Earth and the Sun, making it largely invisible from Earth. This occurs because the side of the moon that is illuminated by the Sun is facing away from us. As a result, we see no illuminated part of the moon during this phase.
Exactly 50% of the moon is illuminated at any moment. As the moon revolves around the earth and its position changes, the fraction of that illuminated 50% that's visible to us on earth changes.
50% of the moon is always illuminated by the sun (although which 50% it is keeps changing as the moon rotates). New Moon occurs when we look directly at the entire dark half of the moon. Full Moon occurs when we look directly at the entire lighted half of the moon. Of course, we can't travel around the moon to look at different parts of it, so the moon obligingly moves around US, once every 27.32 days.
