We all know that at night, when the full moon shines darkness retreats.
The light of the moon is the reflected light from the sun.
As the moon turns round the earth we see less and less of it's lighted part.
It reduces to a thin narrow band and then disappears altogether.
As it keeps rotating around the sun the thin-lighted part again can be seen till it grows into a full moon.
The moon can only be seen at night. The light of the rising sun is so strong that it chases the moon away during the period that it shines on earth.
It is the heat and ray of the sun that sustains life on earth.
