Light travels in straight lines. A shadow is caused when light beams hit an object and bounce off, preventing the light beams from passing through and hitting the ground on the other side. So when you, for example stand in the sun and the suns rays hit you, the light reflects off you and goes the other way. so behind you no light falls from the direct rays of the sun, so it is dark. The area around your shadow is where the light is hitting and reflecting, so technically speaking there is shadow under them, which is why we associate the ground with being dark. no light.
