The moons reflection from the Sun's light. The light hits the Earth so the viewer can see the moon.
The moon changes phases because different portions of the moon are illuminated by the sun, as seen by observers on Earth. The angle formed by the sun, the Earth, and the moon, is constantly changing as the Earth orbits the sun and the moon orbits the Earth.
Moon Phases , or Lunar Phases.
Venus has phases that can be seen from Earth. See related link for a pictorial.

The moon's phases can be seen from the earth, but not by an observer on the moon. Similarly, the earth's phases can be seen from the moon, but not by an observer on the earth.
because the sun causes ther effect
Only our moon ("The Moon") can be seen from Earth.
no Mars does not go through phases as seen from earth.

That is because we are basically in the same direction as the Sun that causes the phases.
Planets do not have lunar phases because lunar phases are specific to our Moon. However, planets with moons of their own can have similar phenomena called satellite phases, where the appearance of the moon changes as it orbits the planet. Some example of these planets are Jupiter and Saturn, which have many moons.
Since the sun illuminates the moon, no moon phases can be seen from the sun, all moons and planets always are 'full'.
