Answer 2

‘New Moon’ is when the moon is not visible from earth, and the reason it's not visible is because it is between the earth and the sun. It is there all day in the day sky, and the sun is shining on the ‘back’ of the Moon. No part of it that we are looking at is lit by the sun.

Usually when the moon is in between us and the sun, it is actually slightly above or slightly below the sun. On those rarer occasions when we are all in a direct line, the moon blocks the sun, which we see as a solar eclipse.

For the moon to cast a shadow on earth, it must come between the sun and earth to block the direct line of sunlight reaching the earth during day time.

This means the sunlight meant to reach earth is now falling on the moons surface facing the sun with the dark face of the moon facing earth which means you cannot see the moon lit from earth … New moon day on earth.
