Genesis 6-9,Santigui Tounkara

I was very unfamiliar with the story of Noah.I understood that Noah was a big part of what christian's beleives. I think that the story was really interesting and also made me learned something new about an aspect of christianity. Altough I was raised under Muslim beleives, I thought it was interesting to know a bit more about Christianity. I also didn't know that the Bible is considered to be a cultural artifact because it discuss about civilizations over time.

A question I might have after reading the Genesis is: What is the major difference between the Old-Testament and the New Testament.
