There is no contradiction whatsoever in these two chapters of Genesis. Not one has been demonstrated.
But that is what lpetrich did in his post from the way, way, way back machine. He pointed out lots of contradictions in the two differing stories. He handed the myths in your perfect bible the telltale stain of human composition in its opening chapters.
Your bible is a faulty human construct.
Eschew obfuscation. Habituate elucidation.
