I didn't read all of that because it's unnecessary, the cosmological argument fails because all it does is attributes the explanation of the event to a supernatural force which only pushes the link of causation one notch back. The "We don't know how it happened therefore God did it" argument, isn't a valid argument. If everything has a cause what caused God? Then what caused the thing that caused God? Ad Infinitum. When you say "God doesn't need a cause" you're contradicting your previous statement of "everything has a cause that exists". If you say God doesn't need a cause because he is outside of space and time then your pushing your God outside the realm of the arguable, rendering any arguments for or against a God useless. And further how can you justify saying God exists outside of space and time? Because at this point your speculating on conjectures. It would be like me arguing that unicorns prefer carrots over cabbage. Also, if you state God doesn't have a beginning, what stops us from saying the universe never had a beginning? Let's say the energy that caused the universe has always existed. Then Occam's Razor would render the God hypothesis invalid, preferring the natural explanation (and thus simpler) over the supernatural.
Saying "God did it" to questions for which we don't have answers is intellectually lazy. It isn't an answer,all it does is it stops us looking for an answer.
Did you just discovery apologetics? Cosmological arguments galore.
What I often notice with theists is that they're uncomfortable with the answer "I don't know". We don't know what happened before the big bang, we don't know what caused the big bang. Quantum physicists are working on possible explanations but we're still in the dark about a lot of things.
I've only skimmed through your posts but I'll read it more carefully in an hour or two and give a thorough response.
Giddy with anticipation,
