That doesn't sound like any big-bang theory I am familiar with. If you find someone with those beliefs, perhaps you can discuss it with them.
I can only discuss my beliefs and yours as those are the only two with representatives.
There's some irony that you dismiss a non-theistic solution because you don't understand it while simultaniously being critical of non-theists under the logic that "they don't understand it".
Actually, I suspect I understand your theism. Mind you, it's going to be a collection of various causes, and I have not enough information to quantify which combination applies specifically to you; but I do indeed understand it.
I also understand the various theistic arguments. I suspect better than you yourself understand them. I also understand the scientific arguments... not well compared to an astrophysicist, but very well for a layman (and based on your posts signifigantly bettter than you).
All that said: in the end you have a positive claim. You have a reason you believe it, but you don't have support for it. That's fine. What's odd is that you seem to believe you have support for it.
