Since the 'big bang' never happened, I'll take 20 tons of that.
Nobody knows how it all began so one shouldn’t be so quick to dismiss a theory. Maybe the big bang happened, maybe God did it, maybe the answer is so completely beyond our knowing that it’ll take thousands of generations before humans will be able to grasp the truth. We just don’t know.
If you want to go the God route, that’s cool. If someone else wants to go the big bang route, that should be cool, too.
