Is night really a shadow?

What is a night?
Well, its the dark thing or lightless thing, before sunrise and after sunset.
Is that it?

The best accurate and more simpler way is to tell that The Night is the shadow!
Shadow of earth.
As everyone thinks, shadow isn't just the absence of light over a surface ,produced when an opaque object is kept in front of a light source. Instead it is the entire surface of the volume behind this object, where light doesn't occur to illuminate.

If you consider a rectangular book kept in front of you, shadow is not just the rectangular shape we see in the screen behind the book, but the surface of cuboid starting from the text book till the screen.
That surface of the cuboid is entirely the shadow.
Hence, night is just the shadow of earth!
