You are incapable of explaining why there isn’t a progressive, exponential increase in genetic defects, among humans today.
Two beings inbreeding will result in massive genetic flaws, accumulated over the generations. Even if an “immaculate” pair was used, the faults due to this “Fall” would still have to follow an exponential increase, to ultimately affect all individual offspring. It doesn’t manifest in this way, in the human species, and thus, the entire human race of today cannot be traced back to merely two individuals. Genetics doesn’t allow this.
Actually, yes it can, and has been. And don't demand proof, go look it up, I won't cater to your ignorance.
There is no exponential increase because of the social precautions against inbreeding. In the cases where there has been inbreeding, we do see these catastrophic abnormalities, as expected.
Obviously, you haven't visited West Virginia recently. /sarcasm off, but on a serious note, the argument previously presented doesn't entail continuous birth defects in the soulish or physical domain with repetitive sin, although one might make a well justified case that those who dwell in sexual immorality find certain side-effects associated with those decisions which are very real, physically and mentally, for the unrepentant sinner as well as the repentant sinner.
