Is the Afro-Asiatic linguistics incompatible with Young-Earth Creationism?

[Belacqua]

Yes, but not all aspects of reality are equally incompatible with Young-Earth Creationism. Indo-European linguistics is not nearly as blatantly incompatible with Young-Earth Creationism as Afro-Asiatic linguistics is.

There are many kinds of evidence against young earth creationism, and if you've identified one more I think it's good to add it to the list. 

Of course we've all seen that when someone doesn't want his mind changed, no amount of argument will do the trick. Still, it happens that occasionally a person may be persuaded, and every little bit helps.
