The primary argument that religious people use in an argument for God is that there needs to be an "uncaused cause" that the universe came from since something does not come from nothing. This is pretty easily countered in many ways including pointing out that an uncaused cause does not necessarily mean a God, or pointing out that if God existed for eternity before creating everything, at what point in eternity did he suddenly decide to create everything- how did a conscious being like God exist before time? Makes no sense clearly.

But even more relevant than this is the meme that the Universe came from "nothing", which is pretty wrong in the first place. Most scientists now agree that "quantum fluctuations" probably preceded the big bang, and that possibly other universes with different laws existed before us and maybe even in parallel with us. So why are scientists not more keen to point out that the idea that we came from nothing is wrong? Why do so many documentaries about the big bang talk about it being the start of time and energy when those things likely existed before our universe? Is it not more appropriate to see the big bang as merely a new form that reality took on with our universe being created rather than it being the "start" of reality?
