Because the Sun, Earth and Moon are not directly aligned. When they are the Moon does indeed pass through the shadow of the Earth in what is called a lunar eclipse, an event that only happens during a full moon.
However the Moon usually passes above or below the shadow of the Earth.
This is also the reason why solar eclipses do not happen every month.
The shadow of the earth never falls on the moon when the moon is half full.
An Eclipse of the moon occurs when the shadow of the earth's shadow fall on the moon
The shadow of the Earth on the moon's surface is the reason that it takes different phases. When the Earth completely occludes the moon, it is a new moon, and when there is no shadow, it is a full moon.
The Lunar Eclipse..
During a full moon, the moon is on the far side of the earth, away from the sun. In other words, the earth is between the sun and the moon. That means that the sun is behind us, shining on the part of the moon facing us. Therefore, we see the fully lighted side of the moon, which we call a full moon.
The shadow of the earth never falls on the moon when the moon is half full.
New moon (the Earth goes into the shadow of the Moon) Lunar eclipses occur at full moon (the Moon goes into the Earth's shadow)
When the Sun, Earth and Moon are lined up in such a way that the full moon moves into the Earth's shadow, it creates a lunar eclipse.

The earth's shadow falls on the moon only during a lunar eclipse. Eclipses of the moon can have varying degrees of totality. The earth's penumbra (partial shadow) may pass over the moon, or the umbra (full shadow) may pass over some or all of the moon's surface. All of these happen only at the time of full moon. The moon's regular phases are NOT caused by earth's shadow on the moon, as is incorrectly believed by some.
The shadow is caused by the earth blocking the path of the light from the sun casting shadow on the moon. When the earth is not in between the sun and the moon then we have a "full moon."
An umbra.
Because Full Moon is what we see when the moon is out there in the direction where the Earth's shadow is.
