I wonder what it was like to be around when Noah's ark landed. To be there when Shem said to his son, "Go pork your sister" (in order to repopulate the species)....
I'm paraphrasing of course, I'm not really sure if Shem's son's sister was named Martha or not.
The degree of incest alone is enough to turn away any logical rational person from the bible. Of course it had to have begun long before Noah's time, even when Adam and Eve were conceiving, there must have been LOTS of sexual perversions taking place...
This is of course all lunacy, as the human race began with several distinct chromosomes and species emanating from several different gene pools at different intervals. The idea of humans starting with two people is insane. In order to create a species, you have to have large variables of DNA to continue life.
