We actually can notice, that what we see as a moon changes it's texture, but not very insgnificant. And that's actually proves what Tom says about "we always see the underside of the moon", because it's as high as sun.
Another thing about moon is, that it's path resembles the sun's one. after the day ends, we see the moon chasing the sun, using the same path. That's strange. VERY and VERY not CHAOTIC, not as everything in the space(as told to us). Everything about the moon and the sun is very precise, but for all of us it represented as a "magic coincidence". For example RE theory of why we see one side of a moon.
And third thing: look at the moon today - it's beautiful. It has so much power, i doubt sun shine on it, especially if they go the very same way everyday, but somehow we see different shapes of moon...
