Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.

I know of no such reference for a "natural" Big Bang Theory. Must be just another way of referring to the Big Bang Theory with a differing focus (i.e. kind of like the Hot Big Bang Theory).
The Big Bang is the theory that was developed to describe the origins of the universe.
It starts airing this fall. Also, at least two more seasons are confirmed.
