Something like this happens every so often, usually it can be explained quite simply. However many things in the Bible can be explained simply too . It doesnt mean God didnt use a simple method to send a message.
Too bad it always seems to mean something vad, I mean wouldnt it be great if this meant all the lawyers in the ACLU were to become mute? Or perhaps it would mean all Homosexuals would be cured? Or perhaps Islam would be recognised as the religion of hate that it is.
God's message is simple. It is man who quibbles and confuses it. We have a much greater enemy to fight, but instead, we fight amongst ourselves.
