Genesis skeptics will point out that their are four different authors to the book. J, E, P and D for Yawest, Elosit, Priestly and Deuterist. Actually there are 10 different authors of Genesis and Moses edited it and put the book together...Chapter one Genesis uses the word God this, God that. Chapter two uses Lord God this, Lord God that. We see stylistic changes and totally different kinds of writing through the book. Some skeptics say it was used and written by priest for political gain or something along those lines. They are partly right, there were 10 Genesis writers and not four. All ten were first hand wittinesses, giving first hand accounts. Bible says: Mark 12:26have ye not read in the book of Moses, how in the bush God spake unto him, saying I am the God of Abraham, and the God of Isaac, and the God of Jacob ? In this they are clearly saying the book of Exodus was written by Moses (the verse is referring to the account he writes in the book of Exodus). Same with, Leviticus, Numbers and Deuteronomy, he wrote these next 3 books too. Moses was the collector, editor of Genesis. He put it together from ten pre existing clay tablets. Gen 2:4 These are the generations of the heavens and of the earth when they were created, in the day that the Lord God made the earth and the heavens Gen 5:1 This is the book of the generations of Adam. In the day that God created man, in the likeness of God made He him: Gen 6:9 These are the generations of Noah: Noah was a just mand and perfect in his generations, and Noah walked with God. The underlined phrases appear ten different times in Genesis. Moses edited it and put it together and probably God wrote chapter one, then gave it to Adam. Adam then wrote a few chapters, everybody kept adding to it, and by th time you get the whole Creation story Moses puts it together into one edited form called the book of Genesis. So, when you get to Genesis 6:9 These are the generations of Noah: Really that is Noah signing off and then his sons ( Shem, Ham and Japheth) also add their accounts. This follows in Gen 10:1 Gen 11:27 Gen 25:12 If you are reading through Genesis there are parts that seem unrelated. Like who cares about all the Dukes of Edom ? All those Dukes in there stuck in the middle of the book. It was just a different writer really, giving a first hand account. Also, it is true the Babylonian legend was written down before Moses put together Genesis. The Babylonians had finally written down an oral tradition, and after the flood people would talk about the creation, the flood and the tower of Babel. These being three major incidents in human history. People would talk about these for generations. There are many flood stories and creation stories, and tower of Babel stories in cultures of the world. And the Babylonians wrote theirs down, before Genesis. But, Moses had the actual clay tablets of the original story. The real deal. They Babylonians had an oral tradition that went on generations until it was written down before Genesis was. Just because the Babylonian story was written first does not mean it was first. So, in the end TRUST Genesis it is a eye witness account of the creation. Remember Moses lived post flood. It's important to understand and trust Genesis so the world wide flood can start to make sense. Which I want to get to.
