You are asking about two different things. The chief god (also called a "high god") was not always the sun god; sometimes the chief deity was a mountain god or a warrior god or even a god believed to have created the world. But as for sun worship, in many ancient religions, people worshiped the sun (as well as the moon and the sky), because they did not understand astronomy or other sciences; they assumed a god or goddess must be controlling what went on in the sky, and since sunlight was so important, the sun god (or goddess) was a popular deity. In ancient Egypt, which by some accounts was the first to have a solar deity, the goddess Hathor, and later the goddess Isis were sun goddesses, and Ra was an important sun god. Romans worshiped a sun god named Sol Invictus (he was also the patron deity of soldiers). And in Greek mythology, the sun god was Helios.
