Cosmological argument for atheism

[TheDarkestOfAngels]

1 If god exists he was responsible for the big bang singularity
2 The big bang singularity is the whole universe prior to the inflationary event (the bang) of space and time, matter and energy
3 If god exists he configured an orderly big bang singularity to be consistent with the evolution of animate life
4 The predictability of cosmic evolution is restricted due to the breakdown in physical theory occurring at the Big Bang singularity*
5 From 4 God cannot predict nor control the initial conditions and therefore cannot be certain of the outcome
6 From 3 and 5 God does not exist

*This is evidenced from the so called principle of invincible ignorance, from Hawking-Penrose singularity theorem.

Interesting method of using their own logic to disprove the theory, though there are many sorts of cosmological arguements.
The one I'm most familiar with tends to involve there needing to be a 'first cause' to which god itself is excempt from, which has its own logical fallacies.

Were I a theist, I would likely point out that since god is omnipotent and omnicient and exists beyond reality, that the laws of nature that had broken down that early in the singularity's existance would be irrelevant or some other such nonsense. Still, every cosmological arguement explicitly requires a non-evidence based arguement that attempts to rationally prove, at the very least, the possibility or likelihood of god's existance.
However, every such arguement tends to have the following problems:
Use of Ad Hoc arguement - from the attempts at explaining how and why goddunit
Argumentum Ex Culo - comes from all arguements based on religion or faith
Arguement from Ignorance - we don't know because goddunit
Arguement from Incredulity - a universe without god leads to ridiculous things and therefore cannot happen
Arguement from Authority - the bible/quaran/etc says...
Begging the Question - The universe that so easily allows for life to exist seems so perfectly balanced that it begs the question that...
False Dilemma - The beginning of the universe can only happen in two ways: one that makes sense where god makes it or the one that is ridiculous
Negative Proof - You don't have proof of anything when when I can rationally explain that goddunit
Post Hoc - Because the universe exists, god must have caused it

(Yes, I've downloaded a list of logical fallacies that I keep on my computer from Rationalwiki.)

I'm sure there are more, but every cosmological arguement for god's existance from the standpoint of the creation of the universe seems to contain all of these fallacies simultaneously and I'm probably even missing a few that should be up there, but this sort of thing always varies with the arguement and the arguer.

Beyond that, I will say that it's still a better standpoint than any and all creationist arguements, even if it is just a modified 'god of the gaps' since the overwhelming evidence refutes all religious accounts for the genesis of the universe, earth, life, and just about everything else.
