Sure there is. I could tell you that I am a mostly-anon web developer; I could also tell you I am President of the United States, or a founder of a prominent company that came out of YCombinator. For practical purposes you would evaluate my claims based on your wits and perhaps my comment history, and you would believe that one story is more likely than the others.
All are equally possible but not all are equally plausible.
I'm guessing you'd agree with that, but you'd disagree with what counts as credible evidence. Which I can understand. But the idea that you'd see "random guy on HN makes up a theory involving a fictional wormhole from a 90s television show" as no different from Biblical claims is troubling to me, most notably because the narrative itself doesn't make any claim that could be remotely construed to align with that.
