= Reference to Genesis 6: Fallen angels === 
 The term "sons of God" is commonly interpreted as "God's angels".  Note, however, that the word "angel" is not specifically used here in Genesis 6.  The term "sons of God" could very well refer to Seth's lineage as opposed to Cain's (Cain had been cast from God's presence in Genesis 4).   

 Please see the following passages: 

 ==== Genesis 4 ==== 

  

  

 Note Lamech's statement.  God sets himself as Cain's protector.  Lamech, however takes things upon himself.  This may have been representative of the rest of Cain's lineage.   

  

 Genesis 5:6-32 lists the lineage of Seth, which, unlike that of Cain, still existed in God's presence.  The account of Seth's lineage ends with Noah. 

 The depravity that evoked the response in Genesis 6: 

  

 was probably due to the spread of disobedience from Cain's line to Seth's. 

 In this context, the account of "the sons of God" and "the daughters of men" has little to do with "strange flesh".
