One of the common misconceptions about the Big Bang model is that it fully explains the origin of the universe. However, the Big Bang model does not describe how energy, time, and space were caused, but rather it describes the emergence of the present universe from an ultra-dense and high-temperature initial state
You are correct that the Big Bang model does not describe HOW energy, time, and space were created.
However, as your wikipedia link points out, the Big Bang model does speak to WHEN energy, time, and space of our universe were created.
You are trying to explain the origin of the Universe; the Big Bang does not explain that. Now I’m sure there are a lot of people (even scientists) who go around making calculated guesses about this or that, but that’s not science, those are just guesses. As far as I know, there is no scientific theory that speaks of the size of the singularity nor the origin of it.
I am trying to explain that the Big Bang theory indicates (to quote you)
"the Universe as we know it began to exist 14 billion years"
As you point out scientists do not know HOW the universe began, but the Bing Bang theory does indicate WHEN the universe began.
So, do you agree or disagree with the following statements about the Big Bang theory?
The Big Bang theory describes WHEN the matter and energy in our universe began
The Big Bang theory describes WHEN our space/time continuum began
The Big Bang theory describes WHEN the physical laws that govern our universe began
Once we have established that the universe, matter and energy, the laws of nature and space and time all have a beginning, Then even without knowing HOW the universe came into being we can identify some very basic parameters for a cause capable of producing that beginning.
