Where did the Universe come from?
Scientific answer is we don't know.p
We don't need to know where the universe came from in order to conclude that the universe began as a dense region of energy that expanded outwards. In the same way, we don't need to know where energy and matter came from in order to understand how clouds form. You might as well claim that germs causing disease is an assumption because we don't know where the energy for the universe came from.
Yes God stretched out the universe and is still doing so which causes the redshift which tells me the universe is expanding.
I suppose God also causes clouds and infections?
They didn't mention that we also have some blueshift of several Galaxies that tells me everything did not have its's beginning with that little pea sized universe as it expanded in every direction at once.
Yes, there are blue shifted galaxies that are part of our local galaxy cluster due to the fact that we are all orbiting around a shared barycenter. The redshift is for galaxies that aren't gravitationally bound to the Milky Way or our galaxy cluster.
Yes an eternity ago God started arranging everything from some of the energy that was available to Him in the first light period. I don't know how hot pure energy would be, as no one knows.
We know exactly what temperature it was and what the energy came from. Once the universe expanded to the point where the energy density dropped to levels that allowed atoms to form from plasma, light was finally able to move through the universe without being absorbed by the plasma. This is the moment the CMB was produced. We know both the temperature and the cause of the CMB, and it is further evidence by the power spectrum of the CMB which is consistent with black body radiation.
Yes they had to begin to exist somewhere in the creation event as did everything else. God had an eternity to create the heavens and earth in.
I don't see you providing any predictions on the relative isotope makeup of that matter. The BBT does make those predictions.
