In reply to the question in your 12/03 post PART TWO OF THE HIEROGLYPHS (fivedoves.com) was it not forbidden for the children of Adam & Eve to have sex with one another in order to produce children, the answer can be found in Romans 4:15, "Because the law worketh wrath: for where no law is, there is no transgression." And it can be found in Romans 5:13, "(For until the law sin was in the world: but sin is not imputed when there is no law."  So it was not a sin nor transgression for them to have sex with one another to have children together as the law hadn't been given to them.  The law was given at the time of Moses.
