Sky Burial, a template for an alien culture.

http://en.wikipedia.org/wiki/Sky_burial<br /><br />I saw a recent documentary on this, its hard to forget.<br /><br />I was thinking of what aliens visiting earth after all of us are gone and discovering a charnal ground dedicated to this practice - what would they think? <br /><br />Its also a template for something really alien to western culture to pattern an alien culture on. Not perhaps for a PC race but for a race that is encountered.
