Leviticus-another attempt to establish order

Leviticus seems to be another attempt to establish order and coherency in the world after Genesis. The content of the first few chapters of the Genesis is like a free-verse-order of the world. There are no rules as such except not to eat the fruit of knowledge tree. There is no hierarchy as such except human being and others. And most important is there are no moral or ethical rules as such which Genesis' first few chapters try to establish. Its a free-flow-utopian construction which can be desired by any human being.
On the other hand through Leviticus the attempt is to build much more definite social order with definite rules and regulations to guide.........a "statute" in other words. Afterall human being has travelled a long way ahead from Adam to Moses.
In Leviticus 16:29 the same word 'statute' is used making God's intention very much clear.
