Hey, Rob,
Genisis is also the Big Bang, and it's been proven, so why not?
Besides, how do you know it is really "nothingness"? Has it been proven? Maybe there was something at first, how would you ever know?
But if there wasn't, it sounds so...weird! create something out of nothingness? Yeah right. They say two particles crashed. Uh huh, but that's not exactly "nothingness", right?
Two particles are something. But what particles?
