Everything from nothing, the Big Bang Theory is a general idea that reality had a point from which it began. I posit a completely different model. There is a constant increase in the mass of the universe as it comes into being everywhere. Our concept of the universe having a centre point is merely the red shift of inflation away from us. 13.700,000,000,000 (13.7 billion) years is not so much the age of the universe, it is the limits of the ability we have to see.
