Because a shadow forms behind an object when a light source shines on it. This happens because the object is solid and light can not travel through the solid object. The light that travels around the object reflects back up and the area that is not reflecting looks darker.

That's why! Did this help you?

A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light. The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the lengths of shadows change.

An astronomical object casts human-visible shadows when its apparent magnitude is equal or lower than −4.[1] Currently the only astronomical objects able to produce visible shadows on Earth are the sun, the moon and, in the right conditions, the planet Venus.ngs so that the shadow is less than "perfect"

How is a shadow produced?

Shadows are formed when light shines on an opaque (solid) or translucent (partially solid, like a net curtain) object. This object stops the light rays, so a shadow is produced in the shape of the object. For example, if you hold your hand in front of a light, then the light will only be seen in the places where your hand is not blocking it. You will then see a hand shaped shadow.
