sith- jake the peg, posted something some time ago, which i have the persuasion to go along with. it was along the lines of vacuum, quantum mechanics and virtual particles, something out of nothing. he obvioulsy put it much better than i ever could. even though our minds are unable to deal with the concept, we have to be open to the fact that before the big bang, before the universes collided and before that etc, that there existed : nothing. no ex nihilo nihil fit.
"Nothing exists except atoms and empty space; everything else is opinion." - Democritus of Abdera
"In the very beginning there was a void—a curious form of vacuum—a nothingness containing no space, no time, no matter, no light, no sound. Yet the laws of nature were in place, and this curious vacuum held potential."
