And what do you two find to be a more rational explanation that is not based on faith?
Explanation for what?
You rely on faith as much as I, possibly even more so. You see, all beliefs [religion, or lack there of] depend on some sort of faith.
That's certainly not true of agnosticism, nor, really, of atheism. Agnosticism relies in no way on faith. Very much to the contrary, agnostics simply decide to draw no conclusions without some rational basis to form one. To an agnostic, believing in any particular God, among the thousands of Gods who have been proposed over the millennia, is, without any evidence, no more rational or irrational than believing that a particular random named Jorik lived in a village in some random place 18,000 years ago. Could have happened. There's no reason necessarily to disbelieve it, but without evidence that someone named Jorik lived in that village 18,000 years ago, there isn't really a basis for believing it was true, either.
Now, you might think that the evidence for the God you believe in is a lot more plausible than the evidence that might exist for old Jorik, but an agnostic doesn't find your evidence persuasive, for largely the same reasons you don't find the evidence of other religions persuasive.
As for myself, I'm a Catholic, but my faith has really been devastated by the child sex scandals. I do operate more on reason than on blind faith, and that threw me for a loop, because one of the more egregious child sex predators was a priest that I absolutely adored as a kid. When I turned 16 and got a car, I had him bless it with holy water and all that (I totaled it and scarred my face for life in that car six months later). Finding out that he'd been buggering little dudes my age when I was 9 was devastating. It destroyed the whole underpinning of my faith, which was, essentially, the Invisible Hand theory. The non-existence of the Invisible Hand was pretty much proven to my satisfaction, and that means that everything I relied on in my faith was shown to be unreliable. I feel cheated, because I want to believe, but my faith is just not what it used to be.
That, and the Book of Job. Reading the Bible from cover to cover, especially the Book of Job, diminished my faith every time.
Rumor is, that when Ian's chojubai isn't doing well, he'll even pray to George Bush
There are no atheists in foxholes, and there are no atheists during an emergency repot.
