Isn't Christianity Monotheistic?

We are now interpreting the Bible(King James version) in class. Today, we noticed that in chapter 1 of Genesis, there is God, and in chapter 2, there is Lord God. Why the two God's? I thought Christianity was monotheistic. When Lord God first appears, it is when he is making Adam and Eve, and in the third chapter we hear him speak. Lord God speaks in a way that reminds me of Shakespeare: think words like thou, shalt, thee. Chapter 3 is all about the grden of eden and how Adam and Eve ate the forbidden fruit. In chapter 4 the Lord comes out. Is the Lord the same as Lord God, or does the bible have Lord God, God, and the Lord? Maybe I'm just over analyzing.

Our class has noticed that Adam is a big oaf and Lord God is confusing. We made our discovery of Adam in the book Ladies and Gentlemen, The Bible!, a funny retelling of bible stories. In the book by Jonathan Goldstein, the Garden of Eden is seen as a village and Adam is seen as the village idiot. In the bible we receive evidence of this after Adam tell Lord God "The woman whom thou gavest to be with me, she gave me of the tree, and I did eat." So if the woman gave you a gun to put to your head, would you shoot yourself?

Something else that I never thought about is how confusing Lord God is. First, why would he plant the tree if nobody was supposed to eat from it? And if God knows everything, wouldn't he know that Adam and Eve were going to give in to temptation? Was it all a test? I bet they failed...poor suckers.

Adam and Eve have two children, Cain and Abel. Basically, nobody likes Cain because they are too busy worshipping Abel and when each brother presents a gift to the Lord, He neglects Cain's gift and accpts Abel's with open arms. Something clicked in Cain's mind and he got sick of everybody loving Abel, so he performs a sinful act and kills his brother. Talk about sibling rivalry. Later, Cain meets his wife and they have a child, Enoch. And Enoch has his son, Irad, and this cycle goes on for a few sentences. Meanwhile Adam and Eve have another son, Seth to replace Abel, and the whole reproduction system continues.
