It's kind of cool.
But those journalist ( digitaljournal just lost a credibility I never gave them) , are really pushing the sensationalism a tad too much.
Ok it's written on a parchment older than Muhammad birth. Parchment were a rare and precious commodities. Pretty normal to write on old parchment.
That the same argument for the forgery of Voynich manuscript. Having an old vellum does not mean it was written at the time the paper was created.
But for that dumbass journalist, it's an older parchment therefor it's written before Muhammad. I prefer considering that Brian Booker fellow as dumb, than mean-spirited. But.. oh ...
