@Fil Albuquerque,
Well, there is a linear model of progression that the big bang theory is built upon.
It starts from a single explosion, expands into more complexities until suddenly life, yet another level of complexity, happens. Then consciousness, as an element introduced at last. Generally speaking this is the progression.
But where does this linear progression idea come from? I will not claim to know that specificaly, but I know one place where one is found that is remarkably similar. Consider the linear progression of the biblical genesis. One god, makes heaven and earth, makes water and sky, makes animals, and at last makes man and woman (consciousness) and puts them into creation upon its completion.
Now consider that the big bang theory was originally proposed by a
priest. It is not such a unlikely scenario that he chose his conceptual understanding of linear progression he got from the biblical genesis as a framework to construct his theory.
If the maker of big bang theory had come from a hinduistic background it is not at all certain that the theory would be even close to what it is. Then the cultural beliefs that prevail in hinduistic societies would likely be the conceptual frame he sought to mold his theory by.
