But how do you expect science to show that the universe either does or does not require a God? That's a pretty tall order, general_re. Frankly, I don't think this is a scientific question at all. One must run on over to the other side of the great epistemic divide (e.g., to philosphy, cosmology, theology) just to ask it.
My best wishes to you and yours for a Happy New Year!
It all began with that atheist Newton and his laws of motion, which denied the God keep pushing the arrow continuously in flight.
I shouldn't have to point this out, but asserting that things behave in consistent ways over time does not deny God, even though it sometimes denies the need to assume miracles in everyday life.
If you assume miracle as the default explanation for an unknown phenomena, you cannot do science, because science has the opposite default assumption.
