[fire and forget]

I suppose the Sumerians and the Akkadians might have had a tenth-planet answer to the questions we're pondering today in connection with our origins. Or maybe we're still a long way from completing the puzzle even if we've managed to eliminate various possibilities with the same empirical science that has put us today in command of great technologies and a vastly better grasp of our universe. (Notice please my deliberate ommittance of any tin hat references) :). All I know is that I just don't know. Hopefully we'll work it out in my lifetime.
