Someone has to explain to me how man populated the earth without it? From a practical standpoint, God let men live for hundreds of years in the begginning, and it was to poulate, I assume. They had to have multiple "wives" in order to do this. As time went by, and the popualtion increased, God shortened the lifespan. Even after that, there are rightous men in the Old Testament that had slaves and concubines, as well as more that one wife. In Jesus's time, Jewish men were allowed to have more than one wife and some did so. Jesus never once mentioned it (Polygamy). If it were the sine we seem to think it is, it seems He would have addressed it. On the same topic, sort of, I have always wondered how mankind sprung from Adam and Eve if there was not incest involved in the beginning. I am not making a case for it, just cannot believe that it was not acceptable at the beginning, and as time went by it was not, God had to have granted man a grace period for it to work without the birth defects and other issues that arise from it today. Going from memory, was it the book of Leviticus that finally addressed the matter, when the earth was off to a good start population wise? Just my thoughts and I admit I do not know the real answers to this.
