Steinbeck wrote that we are all descendants of Cain, so everyone took that up, but we are not. After Cain killed Abel, Adam and Eve had more children, specifically and first, Seth. It is from Seth that Noah is descended, and therefore, all of us. But, Seth and Noah were descended from Adam and "therefore all marked with sin." Adam is the original sinner.
