I presume you are referring to Jesuit priest Georges LeMaitre, the one who first developed the idea now known as the Big Bang.
Arthur Eddington was probably the main supporter of LeMaitre's ideas; Einstein emphatically dismissed them. Edwin Hubble never made any direct statement about BBC, but he did show that one of its predictions was, in fact, correct.
The Big Bang is a theory in cosmology that explains the origin and evolution of the universe, supported by a significant amount of observational evidence. It is not a hypothesis, as a hypothesis is an initial explanation to be tested and either supported or rejected based on evidence.
Evidence. See related question.
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.
the big bang theory
The 1964 discovery of cosmic microwave background radiation supported the Big Bang theory of the universe. This radiation is considered a remnant of the early stages of the universe when it was hot and dense, aligning with the predictions of the Big Bang model.

The Big Bang Theory is set in Pasadena California.
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Big Bang Theory is available for rental only.
The duration of The Big Bang Theory is -1320.0 seconds.
This theory is known as the Big Bang theory, which suggests that the universe started from a very high-energy and dense state and has been expanding ever since. The Big Bang is supported by various lines of evidence, such as the cosmic microwave background radiation and the abundance of light elements in the universe.
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).
