Lilly, I will shoot you my email address and we can discuss this at length. Or, if you want my cell, we can chat. I have AT&T. If you do too, talk is free which is about a cheap as you can get.
But to answer your question, I am saying that Christians take the account too literally. The Bible is full of history, legends, myths, metaphors and allegories. It is written that way to to cause you to ponder the Lord, your life and creation.
Although Jews are free to interpret the Bible any way they wish, most Jews agree that we are born innocent. We choose to do right or wrong--Satan, Jesus and "original sin" are not factors in our life's story. By saying that Satan is in charge of this world, Christians are giving too much power to Satan. We find this appalling and a form of idolatry.
Judaism is about life. It is a religion of life. We believe that you are to embrace this life as a gift from God. We do believe the world is broken and it is important to perform mitzvot to help the Lord repair it. To give up on this life and not accept personal responsibility is a grave sin. No mediator is necessary in your life because the Lord loves you and welcomes you. Besides, if you take care of this life the one to follow will take care of itself.
I could go on and on....we can talk later. And if you really want to know about Judaism, you can look over Judaism 101. Although it is from an Orthodox Jewish viewpoint and I am a reform Jew, I think it is still a helpful site. http://www.jewfaq.org/toc.htm
