Tentatively Christian; looking for a reasonable discussion

I'm sorry, but almost everything here is absolute garbage so far as refuting the first-cause argument.

Absolutely correct. They just keep knocking down straw men. When someone points to the error of their ways (trying to translate the Scholastic tradition into the language of modern analytic philosophy), they just prop the straw men back up and start over.

I think it's very telling that the atheists all respond with lengthy critiques of the argument, while the theists can't muster anything more than a weak "you're wrong and your arguments are bad." At least have the wherewithal to attempt an argument, theists.
