We continue our exploration of author and ancient-alien researcher Zacharia Sitchen's research into the Biblical book of Genesis. Who are the Annunaki, our ancient alien slave masters? How did they come to create  man-kind as we know it today, and how is this knowledge hidden in the book of Genesis that we all know? But most importantly, why do they keep marrying their sisters? All this and more on this week's Cryptic Accounts.
