As @mattbrowne says, both are indeed important subjects for higher education They are also important for understanding how human beings operate as a cultural species. So much history and literature are built upon one or the other and sometimes both, that to fully comprehend (and actually enjoy) people outside of ones immediate family requires and understanding of religions and mythology, both past and present. It can also give some insight into what people may do in the future as well as an insight into current events.
Just think how much smoother American relations with the Middle East might be if all politicians, military men, and diplomats actually understood how Jews and Muslims are taught to view historical and current events.
