You can't get something from nothing. Usually. But way back when there was nothing a lot of something was born. How?

Getting something from nothing is difficult to comprehend. But it's easy to see how often you nothing from something. Something degenerates and VOILA! Nothing. Of course Magicians create illusions that make you think otherwise. An empty hat from which a rabbit appears. How do dey do dat? Of course you can make something out of nothing figuratively.
