The point is that if someone does claim that the dragon exists, they better be able to explain how they know it exists.
Imagine you are a pigeon with navigation magnets in your head. And imagine asked by your friends without it "How do you know it is the right direction?", at some point you have to say "I just know it dammit!"
And imagine pigeons haven't yet figured out magnetism. So it ain't possible to explain it by any means known to them.
Carl sagan's logic breaks down at this point.
As Dr. Sagan (quite correctly) pointed out:
Extraordinary claims require extraordinary evidence.
1. Sagan's example was a metaphor for an unfalsifiable hypothesis;
2. Dragons (okay, kimodo dragons do, but that's orthogonal to the discussion) don't actually exist;
3. Even if dragons with the properties posited by Sagan actually do exist, Evidence must be provided to confirm the "garage dragon" hypothesis or it's irrelevant. If it cannot be detected, it may as well not exist.
While it's true that "Absence of evidence is not evidence of absence," not being able to verify the non-existence of something doesn't confirm its existence.
I suggest you use the rest of the tools provided in Sagan's "Baloney Detection Kit" (helpfully linked above) to help you get the point.
I'd also point out that the guidelines[0] say:
Please don't comment about the voting on comments. It never does any good,
and it makes boring reading.
QFT posits that the graviton (as a particle-like excitation in a "gravity field") exists.
We do not currently (although there are some potential future experiments that might be able to confirm the existence of the graviton) have the means to detect gravitons.
Does the graviton exist? I don't know and neither do you. And we won't, unless and until we have the ability to detect gravitons. While we have a theoretical basis for gravitons, we have no experimental or observational evidence. Does that mean we should stop looking? No.
How about dark matter. What exactly is dark matter? We have a bunch of evidence that something that doesn't interact via the photon (the particle-like excitation of the EM field), but does interact gravitationally with itself and other fermions and bosons.
We don't know what that "dark matter" might be, but we continue looking for it, as there is both theoretical and observational evidence of its existence.
As for the "garage dragon," there is no theoretical, experimental or observational evidence for it.
There is also none of that for my claim of the absolute existence of a gremlin living inside your skull chowing down on your brain. But we should definitely saw open your skull to prove it, right? I'm partial to circular saws, but we can go with a chainsaw if you like.
>you sound like someone who stops giving up at the first obstacle.
It's not clear what ad-hominem attack you're making against me here as the words, as strung together don't make sense, but who I am or what I will or won't do is irrelevant to the discussion at hand.
Are you unable to make a better argument and so attack me personally instead?

Did you? Thanks for finally following the site guidelines. Perhaps next time you won't need to be reminded.
You did a good job at making my point for me, thank you.
The Rabbit's Thesis
Scene: It's a fine sunny day in the forest; and a rabbit is sitting outside his burrow, tippy-tapping on his lap top. Along comes a fox, out for a walk.
Fox: "What are you working on?" Rabbit: "My thesis." Fox: "Hmmmmm. What is it about?" Rabbit: "Oh, I'm writing about how rabbits eat foxes."
(incredulous pause) Fox: "That's ridiculous! Any fool knows that rabbits don't eat foxes!" Rabbit: "Come with me and I'll show you!"
They both disappear into the rabbit's burrow. After a few minutes, gnawing on a fox bone, the rabbit returns to his lap top and resumes typing.
Soon a wolf comes along and stops to watch the hard working rabbit.
(Tippy-tap, tippy-tap, tippy-tippy-tap).
Wolf: "What's that you are writing?" Rabbit: "I'm doing a thesis on how rabbits eat wolves."
(loud guffaws). Wolf: "You don't expect to get such rubbish published, do you?" Rabbit: "No problem. Do you want to see why?"
The rabbit and the wolf go into the burrow, and again the rabbit returns by himself. This time he is patting his stomach. He goes back to his typing.
(Tippy-tap, tippy-tap, tippy-tippy-tap).
Finally a bear comes along and asks, "What are you doing?"
Rabbit: "I'm doing a thesis on how rabbits eat bears." Bear: "Well that's absurd!" Rabbit: "Come into my home and I'll show you."
SCENE: Inside the rabbit's burrow. In one corner, there is a pile of fox bones. In another corner is a pile of wolf bones. On the other side of the room a huge lion is belching and picking his teeth.
MORAL: It doesn't matter what you choose for a thesis topic. It doesn't matter what you use for your data. It doesn't even matter if your topic makes sense. What matters is who you have for a thesis advisor.
His claim wasn't that invisible dragons don't exist. His claim was that you cannot tell the difference between a dragon that doesn't exist and one that is, to use your qualifier, currently undetectable by any means known to humanity. If you cannot tell the difference between existence and non-existence of something, any claims to its existence are vacuous.
But does that stop you from claiming its existence (last second's)?
So as I said in another thread. This logic is completely ignoring the sea of subjective experience that we live in.
“Oh, it doesn’t show up on thermal? That’s because it doesn’t emit heat. It has special fire”
“Oh, when you spray flour in the air nothing sticks to the dragon? Well that’s because it is also incorporeal”
Skeptics keep asking questions. That’s the point. If you are never satisfied with any answer, you have no reason to believe the claim. There is literally nothing there to believe in.
His point is that skepticism and wonder go hand in hand. One without the other is dangerous. What a fascinating claim, an invisible dragon! It should not be dismissed outright as obvious quackery, but let’s see how much scrutiny it can take
We start with an invisible dragon and the more we look into it we now have to explain fire without heat, bodies without form, etc. gee, it seems that for this to be true our entire understanding of the world is wrong…or is the simple answer that someone is trying to trick us would answer this better.
Then the skeptic starts asking why someone would want to trick us…
That makes Carl Sagan's claim some what Balonish. Not sure why the smart Sagan fell for it.
