in simple terms the bible said, there is a god.
it contains, the history of how, god made the world, took some people , that grew to became a jewish people.
through the birth line of this people , jesus was born. and through jesus, death was conquered. so death is not the end,
yet mans understanding developed through era to era, ie learning in many different subject, god talking and leading some,
to different countries\people\ etc
note, not all people in the bible were\ have the same standards or understanding that we have in 2015 in how to treat each other (to keep it short) or spoke the same lauguage . the bible is now wrote and translated for different speaking people. etc
