Where did it start? It is known that there was nothing before the beginning; only the space was there, then, some fluctuation happened, and the Big Bang happened. String theory also says the same. It says that at the base of any matter, there is an atom, molecule, nucleus, proton-neutron pair. Inside Proton, there are particles; inside the particles, there is space. Inside the space, if you zoom in, there is vibration. This vibration is what it born at the time of the birth of this universe.
Another theory says that there is no start to this universe. It is like football, no starting point and no end point. The world is what it is.
The question is, what is the truth, and why are we unfamiliar with it? Is there anyone who knows it all? Is he God or the energy that knows it all?
