Rendered viewport shading shows dark image

Hi everyone, im a new user of blender and i was trying to follow a tutorial and ran into a problem because it did not go for me as the youtuber explained. when i press viewport shading i do not get a instant lighting on my objects. instead it turns very dark , i would even call it a silhouet of the object.
its very hard to get to learn this program wich already is very big and confusing for a noob if in the first tutorials i follow my program does different things then showed.

I suggest you post this on blenderartists,org, as this is a very basic starter question.
This forum is not really for that kind of questions. :wink:

happy blending.

oh im sorry. i did search for blenderartist , got the wrong link apparently
