Christians answer me this. Adam and Eve lived in paradise. They didn't have a care in the world,........?

Yes, the bible is full of flaws - if it were true, we would all be products of close incest and probably be walking around with elephant trunks or some horrible disfigurement as a result. Point is, people made these things to teach a general lesson, or provide an improbable explanation for things. They aren't to be taken heavily or interpreted to the word. Nobody should believe that everything in the bible is literally as it seems, or could be seamlessly translated to life today. In my opinion, those who do aren't reading between the lines and probably dont understand their religion as well as they could.
