Um --- first of all --- my challenge is for you to show it --- not me.
And second of all, due to repeated requests, I actually did answer my own challenge with --- dare it say it --- physical evidence. And more than once.
You must have been absent those days.
You have physical evidence of creation? Hot-diggedy! Oh wait, you meant that rather weak claim about the total mass/energy in the universe. Since that is, and will, with fair certainty, forever remain, epistemologically unaccessible to us, it doesn't really work as evidence, does it.
You know, for potential evidence to "count" it has to actually be possible to obtain it.
Although, if you want to press the point go ahead - then we can claim you don't have the necessary evidence to show that the universe was created ex nihilo.
Oh, and on "the point" of your challenge. The point wasn't to get us to do anything, AV. It was rhetoric - pure and simple - you didn't
want an answer, you just wanted us to say, "Oh, ha ha, very clever AV I see what you did there, I am now a young age* creationist" Of course, this "point" was silly and, because you were unwilling and unable to replace your rhetoric with actual argumentation, your thread fell flat on its face - each of the three times you posted it.
We answered your challenge truthfully, AV, but when presented with a challenge of a similar nature, you suddenly become less talkative. Perhaps that's because you know that unlike in your thread, where it's just rhetoric, you know that I'm not just going to listen to your answer in silence, but actually call you out on the inevitable incoherence and contradictions.
