It may help some posters' propositions if they read the (populist) definition of the
Big Bang, which explains that there actually was "something there" before the initial event -
" In the most common models, the universe was filled homogeneously and isotropically with an incredibly high energy density, huge temperatures and pressures, and was very rapidly expanding and cooling. Approximately 10−37 seconds into the expansion, a phase transition caused a cosmic inflation, during which the universe grew exponentially."
btw, "Big Bang" was a radio-friendly term coined by (Sir) Fred Hoyle, not an actual description - this
graphic timeline may help, as it shows it was approx 300 million years after the event that the first galaxies and stars form.
