New Moon - The relative positions of our Sun, Earth, and Moon, cause these changes. We have a “new Moon” when our Moon's orbit around Earth moves it between Earth and the Sun. From Earth, the Moon's surface looks dark because the illuminated side is facing away from Earth.

In short: We have a “new Moon” when our Moon's orbit around Earth moves it between Earth and the Sun.

Waxing Crescent - The Waxing Crescent Moon starts as the Moon becomes visible again after the New Moon conjunction, when the Sun and Earth are on opposite sides of the Moon, making it impossible to see the Moon from Earth. During this phase, the lit-up part of the Moon increases from 0.1% to 49.9%.

It's really hard to find something perfect.
