I contend that the Big Bang does indeed suggest a creator god. One must remember the Augistinian cause which, despite disagreements to it, holds a known scientific basis for its trustworthiness: something cannot come from nothing. F=ma, any way you slice it. Things are caused. The Big Bang (which I contend, as a professor on astronomy, has been badly named) is a unique event in that before its first planck-time moment, none of the known quantities of physical reality existed; neither time, space, mass, energy or gravity existed. Technically, there wasn’t even a nothing, as nothing implies a something to signify it is differentiated. Be that as it may (and apologies for attempts to get brains wrapped around THAT one!), the Big Bang was the prime expression of the physical Universe. It was a definitive beginning with that ushered into existence a physical reality called the Universe. Simply put; someone (God) had to create and throw the switch to begin it.
And before detractors clammer to suggest the multi-verse' version, note that as reasonable creatures with reason enabled mind, Occam's Razor still stands: adding multiple universes to increase the mathematical probability of our Universe eventually creating’ life is just adding the number of dice to a bucket in hopes that a few more of them will probably' roll out a one. This is not science; this is pseudo-science of the gaps’.
Bottom line: there was nothing, there was everything, instantaneously in all places, allowing for physical laws to rule over the quark-soup to disperseit all into the matter, energy , time and space we now know, see and observe. As a scientist, I do not need to add `unseeable-dice’ to the bucket. I go on what we know: there was nothing, and something HAD to cause the something.
I believe that Big Bang instigator is God.
