Nope. No good at all. The dictionary doesn't define god as just the supreme being. It also defines god as one of several deities. It doesn't agree with you at all."the one Supreme Being,"
Couldn't have said it better myself.
Well done.
Jan.
So stop evading. Explain the difference between one supreme being and several deities. Remember that the context of this thread is whether or not it's even possible to disbelieve - so tell us why the difference between one god and several gods has any significance. If you can believe in one god, why not several? And if you disbelieve in gods number 2 and beyond, why can't you also disbelieve in god number 1?
