Meh, it is impossible for the universe to have sprung from a singularity.
If all the matter of the universe was in one point, that point would be a black hole from which nothing could escape. Scientists know that, so they have to assume that the normal laws of physics did not exist at that point, in order to make the hypothesis even seem possible. However, if the normal laws of physics did not exist, then it becomes impossible to speculate any further, since we can only extrapolate if the conditions remained similar to what we observe today.
So the “Big Bang Theory” disproves itself.
Look up the inflaton field.
That’s why it’s a “singularity” (if you understand the scientific meaning of the term). Dividing by zero gives strange results, but are still consistent with the normal laws of physics.
Matter DOES spring forth from nothing. Happens all the time, just on a very small scale and with meaningful consequences being statistically very rare (but not zero!). Yes, it’s been observed. Particles & anti-particles do appear, and typically don’t get far before they rejoin their partner and annihilate back to pure energy. Once in a while something else interferes, allowing the particles to continue existing.
If you took all the matter out of the universe and squished space down to a point, you’d have a speck of pure concentrated energy - without form, and void.
That speck would expand, given the concentration of energy, and give room for that energy to chaotically vary between concentrations and absence of electromagnetic waves - separation of light and darkness.
As noted above, that energy would spontaneously form into particles, which in close proximity would interact and start separating into viable matter - void from uni-phase matter one could colloquially call “water”.
Matter would start separating into various states - gas from fluid from solid.
Over a long time, as the space expanded and matter congealed & (in some case) cooled, gravity would start forming what we see now, discernible celestial bodies would emerge, and on the vastly enormous scale of chemical interactions, reproductive bodies would form & grow - plants (broadly defined) would arise.
Of note, one moderate-sized star’s system formed an orb unusually conducive to this chemical process, and a moderate-sized rock orbited it - the Sun, Earth, and Moon.
Over time another kind of life emerged on this planet - wild animals of various kinds.
Eventually, God (involved somehow in all of this) directed the emergence of a creature mirroring Himself - mankind.
And in all this, God - being timeless and seeing a day as a thousand years and a thousand years as a day - viewed all of this as being in six phases He called (insofar as our puny minds can grasp His thoughts) days.
And it all turned out pretty darned well.
Works for me. I don’t see the problem.
