Is there a place on the Earth where you will never see the Moon?


There are no places when you would not be able to see at least some phase of the Moon. The exception being if your local geography precluded a view of the southern horizon lower than 30 degrees, for example, if your village was in a canyon or on the north/south side of a mountain range.

The orbit of the Moon is inclined by 5 degrees to the Ecliptic plane, which is in turn tilted at 24 degrees to the celestial equator. This means that in December, the Moon in Taurus is at a declination of as much as +30 degrees, and in June, the Moon could be as low as a declination of -30 degrees. This means that even if you were located at the north pole, the Moon would be seen 30 degrees above the horizon, and a the south pole, by the same amount. From the North and South Poles, the moon would be above the horizon for two weeks at a time from rise to set.
