Four proofs of the nonexistence of God

[Lek]

We now know for sure that the universe created itself?  That's new to me.  What did it create itself from and how does that prove there is no God?

We don't know it for sure. There's a hypothesis gaining ground the the universe is eternal, which could be true in several different ways. What we see as an origin point may simply be the limits of a cyclic process, or may arise out of the multiverse. Time breaks down and has no meaning at the extremes of the Big Bang or the heat death of the universe, so has no real endpoints. The math indicates that time as we know it doesn't exist as you approach the BB and it is meaningless at the other end of things where everything is evenly distributed and inactive, so there is no way to measure or utilize time.

Just another example where actual reality is more amazing than bronze age fairy tales.

As for how that would "prove" there's no god, it wouldn't. God isn't necessary to explain reality, after all. In any case, your god is an unfalsifiable proposition, so I can't make any supportable knowledge claim for or against it. I can only say there's no substantiation for it and therefore no valid reason to afford belief to it.

When you say "eternal" I assume you mean it always existed and always will; no beginning and no end. When I contemplate that it makes me feel the same as when I contemplate God's infinity and our eternal life with him.
