Where did the universe come from? Atheistic origin science has no answer.

[Wyrd of Gawd]

Maybe the term "created" shouldn't even be the term used in this case.
Nothing created the universe because it wasn't created.
It just morphed ...(from a toaster maybe?)

Abiogenesis on a universal scale! yep ...it started out of nothing. (heavily compressed mind you ...

The main problem in understanding how things came to be is that one first has to understand the concept of what nothing is.  Now the funny thing is that anyone who knows the basics already knows that nothing is the source material for hydrogen.  It's just that it's difficult to understand the properties of what we call nothing.  Although celestial hydrogen does come from nothing it just doesn't pop into existence fully formed.  It's the culmination of a very complex process that transforms elemental particles into celestial hydrogen gas.  And once the hydrogen gas has been created the process of celestial creation really takes off.

The hydrogen clumps together, creating dense balls of hydrogen that go nuclear and turn into stars.   The star process cooks the hydrogen into heavier and more complex elements.  Eventually various planets are formed and the planets continue to make their own elements and chemical compounds.  At some stage under the right conditions the planets produce living molecules which evolve into complex life forms, such as what happened here on Earth.

It also shows why the Big Bang Theory is rubbish.
