I have heard that the moon is getting farther away from the Earth, why is this?

Oh, that’s easy!  The Earth orbits the sun in an elliptical path.  Because of this, the moon’s orbit is slightly eccentric, which means it’s a little closer to us when it’s on the “near” side of the earth, and a little farther away when it’s on the “far” side.

The moon is gradually receding from the Earth as a result of the tides.
