You can't see more than 50% of a large orb. Or do you mean why is only half of the half moon that we can see illuminated?

Because it is currently halfway between new moon and full moon. https://www.ducksters.com/science/phases...

Because only one side of the MOON always faces the Earth as it circles it. It is "Tidally locked", so we never see the other half of the moon (Not from Earth anyways)

When we see the half-moon, the Earth and the moon are about the same distance to the sun. (From the moon, you'd see the half-Earth, also.)

Because the angle between the Sun, Moon and Earth is a right angle. Now work it out.

Because the dark side of the moon cant be lit up from the back...the sun only shines on the front part and now were looking at it from the side.

Because of where the Sun is relative to the Moon. The Moon, as seen from Earth, goes from fully illuminated to fully not, every two weeks. Really, go read on Wikipedia, this is very basic stuff.

Because the angle between earth, moon, and sun is currently about 90 degrees.
