Mysteries of the Bible

Some of the teachings in the Bible are a mystery.
Did the garden of Eden exist in real sense,since we're told the garden was surrounded by rivers such as Euphrates and Tigris?
What became of the people who were raised from death when the world shook after Jesus died?

 

There are definitely mysteries of the bible, but I also look at it more in the sense of the telephone game. The bible wasn't written when God created Earth or when Jesus roomed it, so of course the stories are going to be altered some or maybe even omitted (look at all the chapters that were left out of it). I believe that they are moral teaching as opposed to factual truths (come on Noah's Ark... no way that happened with all the animals two by two). I'm sure many would disagree with me, but anyone who has studied the bible (Christian or not) will find contradictions and mysteries that is up to our interpretation.
