Atheism has nothing to say about the origin of the Universe! You yourself said that atheism is not science - and I agreed. Twice. Do keep up.
My point, since you ask, is that no scientist working in the relevant fields pertaining to the Big Bang and origin of the Universe is claiming what you are asserting they're claiming; namely, that something can come from nothing. That's a creationist position, not a scientific one. I'm starting to suspect that the reason you want to pass it off as something scientists are claiming, solely in order to ridicule the science, is down to your recognising just how ridiculous the claim actually is and a desire to distance yourself from it. Understandable, but disingenuous at best.

At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
