Tell you what--show me ANY objective, observational evidence of your magically appearing apple, any at all (without relying on trickery or sleight of hand), and I'll consider this something more than a flip response.
The Big Bang theory, as I understand it, doesn't posit that the universe appeared from nothing. It says that it emerged from a "dense, hot state"--a primordial atom, if you like. The beauty of it--and what makes it a theory as we define that term--is that it does rest on observational evidence. Take this recent, exciting discovery:

Of course, you can ask what came before that primordial atom and speculate that some grand designer put it into place. But that's not science. It's not a scientific theory. That's faith. That's all I'm saying.
