"My theological argument:"
I appreciated this, ICBINEG. Very raw and honest. Thank you. I'll give a few comments.
"Personal: I have very slight bi-polar personality issues. There are the vast vast majority of normal days (like today - phew), there are rare depressive days when I know in my body, mind and soul that I am hated. The Universe hates me and would destroy me if it wasn't more fun to make me suffer. I have much much rarer manic days when I know in my body, mind and soul that I am loved. That the Universe is looking out for me and my soul will live forever."
This is kind of poetic and heart-wrenching at the same time. You should write a novel.
"Observational: 1. That in the history of humanity we have constantly ascribed the unknowable to mystical agents and that day by day more and more of those unknowable things become known - by which I mean that we can explain them as event caused by nature/chance/coincidence and can be described by a predictive theory of natural science."
Fair enough. But in the 20th and 21st centuries more and more scientific discoveries have seemed to be best explained by intelligent causes and not random-chance processes.
"2. That a decent gamma ray burst anywhere near here would wipe out all life on earth."
Sure. Curious to know why this is relevant, though. Is this a Hitchens thing (since I know you like him)? He always points out stuff like this and then says, "Some design." Is that what you are alluding to?
"3. That a substantial number of other people believe in a higher power all of the time."
True. That could be interpreted as evidence for God's existence, no?
"4. That you can make any atheist believe in God transiently by zapping the correct area of the brain with the right sort of electromagnetic signal."
Ah, I assume you are referring to Michael Persinger's God Helmet here. He is only about an hour and half away from me and I invited him to demonstrate it on a cable access TV show I used to host and produce called 'Beyond Belief' but, alas, he couldn't make it. :^(
"5. That there is a genetic component to faith with identical twins having faith levels that are more correlated than those of fraternal twins."
That's interesting. I didn't know that. However, I have developed my own theory that, since we know mutations generally break things, the design-detector gene (if such a thing exists) in atheists is broken or defective. An evolutionary explanation for atheism.
I would predict that in MRIs there might be areas of the brain which light up in theists in response to certain stimuli that do not light up in atheist's brains. That is a testable hypothesis.
"My Conclusion: That the universe is a cold an uncaring one that will kill us without noticing (because of the GRB's)."
What are GRB's?
"That everything will one day be explained by a predictive theory of natural science (because we heading so fast in that direction - it is only a matter of time before the remaining holes are plugged)."
I predict it won't happen. The elusive Theory of Everything will remain elusive. But how long is reasonable to wait until design becomes a rational conclusion? Forever?
"That people believe in God because of their brain biochemistry, rather than because God exists (because my own brain does it sometimes and the rest of the time the whole idea seems nuts to me, and because you can externally alter the brain to reproduce the effect, and because it is only a matter of time before we isolate the genes responsible for faith)."
So those faith genes would have had to confer a survival advantage. What would that be? And if religious people kill other religious people (because as we know, all the wars in history are religious** ;^)), shouldn't we let them kill each other off so the rational people who have lost their faith genes can rule the world?
**NOTE: Less than 7% of the wars in history are classified as religious. Slightly more than half of those involved Islam - in just the past 1,400 years. We should clearly make a distinction between religions.
