Because they're ignorant, whoever "they" are.
The term "New Moon" does not mean the Moon is directly overhead, it means that the Moon is (approximately) between the Earth and the Sun.

The New Moon always occurs very close to the moon's "new moon" phase.
No. The phases of the Moon are caused by our moon rotating around the Earth. When the moon is between the Sun and Earth, the face nearest to us is not illuminated and in the Moon's own shadow, and this aspect we call 'New Moon'. When the moon is on the side of Earth farthest from the sun, it is fully illuminated, and this we call 'Full Moon'. [Due to the distribution of mass in the moon, it keeps one face towards Earth.] The earth rotates once every 24 hours, so we see the moon in our sky once a day - but sometimes in the daytime - when it is approaching 'New'. But the moon orbits the earth once every 28 days (approx) and this motion is the one that is responsible for the phases of the Moon. !
Yes there is twilight new moon
Both full moon and new moon can be seen at the sunset. But full moon in the east and new moon in the west just after the full sunset.
The New Moon is directly overhead in locations close to the equator but even when the New Moon is directly overhead it won't be visible because the shadowed side of the moon is facing the Earth. Also when the New Moon is directly overhead, the sun will also be close to overhead as well, as the moon is closest to the sun during the New Moon phase.
To be directly overhead the moon must be at the correct latitude. For some locations this is simply not possible because the moon's orbit is nearly in the plane of the equator. For other locations, it is necessary to know the latitude of your location.
The sun can never be directly overhead anywhere in New York state ... or anywhere in the USA for that matter. The highest it can ever appear is at noon on June 21. But in order to ever see it directly overhead, you have to be located within 23.5 degrees of the equator.
The new moon phase and the full moon phase
new moon
First thing is that it is not the shadow of anything. The side where sun's light is absent. We call it as new moon as a new phase has begun to reach the stage of full moon. Even that might have been named as NO MOON, and misheard as NEW MOON.
A New Moon
I don't know what you mean, the Sun always "hits the Earth directly". A full moon happens when the Moon is opposite to the Sun in the sky.
The Dark Moon, sometimes call "New Moon" is the phase of the moon where it is between the Earth and the Sun and cannot be seen.
New Moon, they call it.
It is called a new moon.
It is called a new moon (tiny part or no part of the Moon illuminated). If the Moon is directly between the Earth and Sun, it can cause a solar eclipse.
