A Crowded Boat Ride
Remember that time God the father was a bit more than disappointed in his creation? When he decided enough was enough, his best solution to the issue was not to hope for change. Instead, he decided to solve his issue with the mild-mannered approach of flooding the entire world. Fortunately, he tipped off Noah first so that humanity could live on.
But it was not just humanity Noah was tasked with saving. He also became responsible for every animal on earth too. Simple telling of that story indicates that there were two of every animal allowed on the ark. But there were actually seven pairs of so-called clean animals allowed on board. That gives each species a much better chance of developing some genetic diversity, don’t you think?
