Are you then saying that a vacuum doesn't fall under the definition of "nothing"?
Of course, a physicist would agree, because he'd know that quantum fluctuations make any "vacuum" seethe with activity. However, that activity is literally "something created from nothing", as it both exists - it is "something" - and it is not created from any other thing - "nothing".
And how does "it is not possible for something to be created out of nothing" apply to my fridge, in which there is "nothing", yet it still kind of smells?
