Is there a single scientist (physicist) who came up with the theory of Big Bang or ... this is a theory that a group of scientists (physicists) came up?

The term 'Big Bang' was first coined by Fred Hoyle in a statement seeking to belittle the credibility of the theory that he did not believe to be true. As far as who discovered it, I think many cosmologist and physicist realized that after the 'Expanding Universe' was discovered that it was a piece of evidence for the 'Big Bang'. Because if the Universe was expanding that meant that it must have at one time been very compact and dence. Then in 1964 'cosmic microwave background radiation' was discovered which also confirmed the 'Big Bang Theory'. The question that I've always wanted answered was how did this very compact and dence object come to be here in the first place? It seems that when a question is answered, more and more questions follow.

Kind of interesting background story.

Given the problems with "dark energy" and "dark matter," I would think the whole Big Bang theory is questionable at best. It is easier to summarize the redefinition of space experienced as the redshift as possible caused by the approach of two great masses (one of which has been identified BTW) and may also account for entropy.
Only flat-earthers can beleive that what we can see to the "visibility horizon" indicates what the universe is about.
