NONE of these stories are completely true...

The Titan story was true.

Oh yeah I remeber that one

No one dies a virgin, Life screws us all

Preeeeety much...there's no guarantee that the "factual" ones truly happened the way they are depicted, or even that they happened at all. Someone might have had some reason to think that they did, or there might have been a natural explanation behind it, or some similar situation. Of course I like to imagine that they gathered as much research and evidence as possible and determined that most of their "fact" stories were likely or very, very possibly true, before slapping that label onto them (dismissing claims that were too lacking in support or verification/corroboration.) Hopefully--but who knows. Maybe sometimes they just needed to dig up some new stories quickly and couldn't be that thorough. I still wish Robert Tralins' research were available in detail on his site. That would be most revealing for fans of this show.

I wonder if they screwed up and invented a story that was close enough to a pre-existing story.

Oh, but the rest of the show is so amazing...! ;o; Even if you watch it purely for entertainment and aren't a believer at all (despite the intro's beseeching you to "break through the web of your experience and open your mind to things beyond belief!") Yes, most of us fans wish that they'd logged the facts about each "true story," and the research and uncovered evidence, into a book or website or something. In fact, I imagine that if she show were being made now instead, that's likely what they would do. But, alas.

I don't think we can legitimately claim that none of those things are possible, and that no such things have ever happened. In any particular case, yes, the burden of proof falls upon the individual saying that something did occur or is so...but no one can say, "I've never seen evidence of any event or phenomenon like that, and it's too hard for me to believe, so that means that it's completely impossible and has never happened to anyone, anywhere, ever." (Well, of course someone can say it...you can say anything...but like most statements, it's a mere opinion and not a fact.)

And I was confused by the last part. Only a story that's non-fictional, or mostly based on non-fictional events, can be termed a "true story." Movies based upon novels and other works of fiction are not "true stories." You don't claim that your movie is "based on a true story" and mean that "the story truly existed as a story before I wrote it as a screenplay--I didn't make it up myself!" If that's the case, you credit the original author/creator, or state the source (such as a certain type of folklore, if there's no individual known author or 'intellectual property copyright holder.') If your point was that filmmakers frequently stretch, bend, and warp the "truth" as far as they can while still retaining enough of the original facts to advertise it that way...then naturally, I won't argue that.
