Carleas: an excellent set of questions. So let's be more specific about extraordinary. Yes. I must convince the judge that it is beyond a "third nipple." In other words: Beyond anthropology in the natural world. Beyond evolutionary mutation. Here's a few examples I would settle for.
"Wow, someone is able to fake carbon dating and insert weird chemicals into tissue as yet never before demonstrated. Whomever the hoaxer is, we should get a hold of their unique technology!"
"Wow, somebody from a millennium ago did some human genome splicing. Guess we had forgotten how to do that for a while."
"Wow. Everything is a fucking illusion, this couch is an illusion, because if you can fake a dead alien skull enough to convince a geneticist, I guess you can fake anything in the world."
Anyhowww . . . yes Paranormal would suffice. But I'll even settle for someone convincing me that it's a hoax that was hard to do. It's too easy for people to guffaw it when there is little motivation. Now someone in a challenge will have to really get technical about it in order to win. Seeing as you posted Carleas, are you considering volunteering for a role at all?
