「斑馬知識+挑戰 」 宇宙的產生是否從「無」到「有」？

Steven Hawking said, 'What did happen before the big bang is out of the science; it is totally a religious and philosophy question.'
At the begining the universe is a extremely small fire ball which density of energy are tend to infinity. At the begin of time, the fire ball explosive and then the universe gradually born.
So what matter come from ? According to E=MC^2, matter can b formed by energy in the fire ball eg: The photon collide to each other to form electron or positron. So matter is formed from energy of the fire ball.
Sorry for i cannot anwser u about wat the fire ball is formed by scientific methods. Personal belif, I believe that the god created the fire ball and then he turned it into our universe
