they really aren't identical. our view of the Moon does vary because the distance to the Moon does vary and because the Moon's orbital speed varies during its orbit.
this is an animation of the Moon made of images made every day for about 29 days, more or less. the Moon appears to grow and shrink as it gets closer to then farther from the Earth. the Moon also appears to wobble from side to side because the Moon's orbital speed overtakes then lags behind its constant rotational speed.

Only one side of the moon faces Earth. It's rotational period is 28 days, unlike our 24 hours.

un you mean why does the full moon look the same in every picture?
The rotation period of the moon (1 lunar day) is almost exaclty the same as 1 lunar year (orbit around the earth) so the earth always sees the same side of the moon.

They are not exactly identical, though they tend to be very similar. I guess that's because the old moon is pretty stable.

That link above is neat. I didn't know the moon wobbled like that.

I have Sean many and I have not Sean even one that is identical.

Because the same side always faces us.
