The world does not exist independently from those that witness it. The sun does not make light without eyes to see it. There is a mutual interdependence between you, or your conscious experience, and the entire universe.
Without you as a conscious being there is no universe to experience, only through our conscious experience does the sun shine light, does the river feel smooth, do the birds sing melodies and do the flowers smell earthy. You are creating the light from the sun just as much as the sun is creating the light, there needs to be mutual interdependence in order for the universe to exist.
You are an aperture through which the universe is experiencing itself. Without you as this aperture nothing would exist and nothing would be experienced.
