In front of you
A shadow forms when an object blocks the path of light. In the case of the sun shining, the object blocking the light is you, which casts a shadow behind you. The sun's rays are not able to pass through your body, creating the shadow on the ground.
The lower the sun is behind you, the longer your shadow will stretch before you.
