The Big Bang Theory
In the begging there must had been initial conditions, the influential factors and the final results which yielded what man and other living organism may see surrounding them. This would mean that the resulting matter is achieved in a process which involves the initial conditions, the internal and external factors.
This same logic is quite imperative when it comes to the existence of the universe. One of the powerful scientific theories explaining the existence of the universe is the Big Bang Theory which explains what happened before, in the process and after. This theory tells that before the universe came into existence, there was nothing. It is like the whole of everything was formless.
