my coworker told me about this part of the story of the tower of babel--nimrod, the king at the time, was the one who built the tower as tall as he could to get to heaven, and then his soldiers shot arrows into the sky. they bragged that the arrows came back dripping with the blood of angels. and that's why god made it so that we all speak different languages--to make it more difficult so we don't all go getting together doing dumb things like that, again.
