<s>[INST] Yes, do you think that sun shadow or the existence of the shadow of a person, an animal or the any object may be of significance, largely in this world driven by science and technology. 

I think that the study of the shadow of objects in natural environment can answer some fundamental questions. Shadows provide useful information and pattern of past, present and future.

Can you please give an insight on the subject of the study of sun shadow including of living being and non-living being?[/INST]
