Light is a consequence of the electromagnetic force.
This force and gravity are the two long-range forces that control the large scales in the universe. Gravity shapes the universe and is probably connected to the existence of space and time themselves. Light, or more generally electromagnetic radiation, fills the universe and was once a dominant factor in the evolution of the cosmos. The strong and weak forces are a bit different from the other two. The strong force's most familiar manifestation is to bind the nuclei of atoms together, acting there as an attractive force.
