Good exists - a Catholic comments

Look up "Quantum Field Theory". Photons carrying electrical forces pop into existence and disappear all the time, every time you touch something. Since low-energy particles do it all the time, it's not a strectch to imagine that a high-energy particle such as one that existed at the beginning of the universe (right before the Big Bang) can pop into existence under some conditions.

Hi Flat,
Yes, you can imagine that, I respect your imagination. 
I happen to believe 100% in God. We disagree. I can cope with that.

But it's a fact that your assertion in the OP that "Science proves something cannot come from nothing." is false, at least ever since Quantum Field Theory was discovered.
