Most of human history, the ideas about the origin and evolution of the universe were considered through philosophy and religion. To make up for the unknowable and unexplainable, stories were passed down through generations. Today we have new instruments that allow us to look into the past and the future of cosmos. There is also evidence behind the big bang such as the redshift of galaxies and cosmic background radiation.
