This is the one of the episodes where Margo, Moki, and Derek are not shown at the actual Biblical events. "The Creation and Fall" are narrated by a storyteller (Les Tremayne who also voiced God). The reason is Adam and his wife were the only residents of Eden. They begot children after the Fall. The first couple's children Cain, Abel, Seth, and unnamed daughters were all born outside of Eden.
This episode featured back and concealed frontal nudity for Adam and Eve.
In real life, Eve was still topless when God banished her and Adam from Eden. She and her husband were both wearing loincloths at that moment.
Like other animated and live action depictions of Adam, he is shown with a clean shaven face rather than having a mustache and a beard.
