@cicerone imposter,
You are the one who are part of that probability. I know that you don't acknowledge any other evidence except for the red shift from the telescope, but the logical inferences and the reasonable ground to believe are also accepted as evidence by some sciences.
If you remember you claimed that it is impossible to know the assumptions of the Big Bang, for if one knows the reason for the creation of something there always remains the question who/what created the reason itself, and after that who/what created the assumptions of that reason, and who/what created the assumptions of the assumptions, etc. So this very question is contradiction within the self, hence it is invalid ... for most of its interpretations. One of the few interpretations for which it is not invalid, is the case when the Universe has always existed and the Intelligence of the Universe has always existed (I don't comment whether this might be God, or String Theory, or a previous ILF, or the previous form of existence of our intelligence). The other few are the case when the reasons for the creation of something have always existed, but they far too improbable.
When you eliminate the impossible there remains the improbable, notwithstanding that it has been always rejected. Have you ever heard about the logical inference based on Modus Tolendo Tolens ('the way that denies by denying'). As it is impossible for the Universe and for the Intelligence to have been created, there remains the exclusive option (although highly improbable and denied by science) for the Universe and for the Intelligence to have always existed, which automatically means that the Big Bang has not created anything, and we are most probably bio-robots on remote control or on relay race switch, or a form of existence of the intelligence in the Universe ... and in the capacity of being so we are most probably obliged to preserve the life in the Universe from extinction and to switch it over to the next inhabitable planet/world or whatever it might be there.
Perhaps you should pay attention that this hypothesis preserves the physical law of conservation of energy (the hypothesis is feasible), and also the math logic laws for the possibility of existence exclusively when being released from contradictions within the self (plausibility) ... and everything is
hunky-dori! lol
Yet there remains some probability for us to be totally missing something ... or misinterpreting the things.
Ah, I forgot the CBR - it comes most probably from the Hyperspace, and our space might have been formed by the constraints imposed from outside - the intersection of two 4-D spaces for example. This also preserves the law of conservation of energy for in this case our Universe is actually an open system with exchange of energy with the outside Hyperspace and there are no problems to exchange Dark Energy and Gravitation coming from the Dark Matter located in another dimension.
