The cosmic dubious big bang

From our previous considerations on this topic, I mean by that: The material universe in the cosmic cycle, and from our jointly developed level of knowledge and the factual understanding, one may be able to understand the enthusiasm. However, with the cosmic evolution before this dubious Big Bang, all of this has next to nothing to offer. Specifically, after I was able to read a little in the archives of mankind from the modern planet earth, I mean that they define cosmic evolution from the beginning of this dubious Big Bang. They connect this, from their point of view, central, cosmic event without restriction with the beginning of the cosmic world, without defining this world in concrete terms, energetically and materially. And by that I mean not only material evolution, but also the biological development of living beings of the most varied kinds.
