While the true answer to this question is as individual as each person, I think most boys look at a girl's breasts because they are curious, and because they find breasts attractive.
They don't have breasts of their own. If you mean the question seriously, there are a number of reasons. Everyone is born with the urge to notice breasts, since that is how infants are fed. Even as adults, comfort can still be found in cuddling and caressing breasts. As everyone is exposed to society, they learn that breasts have a sexual connotation, since breasts are used to feed babies, and babies are produced by sex. So when someone is aroused by women, they may see the breasts in the same or similar way as sexual organs.
