Monk, the only way we could try to prove without a shadow of a doubt that these things are fake would be to travel to every last inch of the globe looking for them and to not find them, and even then there could still be some people who would argue that that doesn’t disprove anything. By your reasoning, even if we could find people who created this hoax and get them to admit to it and show how they built/drew the monsters, it still wouldn’t be proof because there could still be some giant monster dug up from the ice somewhere. Your thinking is along the “if it’s not shown to be absolutely 100% impossible, then it has as good a chance as anything else as being real!”
While it can be said that anything is possible, only some things actually are real. We can’t go out and absolutely disprove everything that’s false in the world. None of us has the time, resources, or ability to do that. We wouldn’t be able to function if we simply went around believing anything and everything; we wouldn’t be able to tell where anything really was or what anything really was. So when something has too much evidence against it, and especially when it doesn’t have any evidence in favour of it, it is considered to be proven false.
These giant monster websites have already been shown to be false on a number of definite and crucial points. Plus, all other evidence that has been found suggests that they are false. There is no evidence in their favour. The people who created the websites are trying to pass off false information as truth. This damages the credibility of all the information that these websites offer, and so we cannot take anything that they have to say as proof of the existence of these creatures. Leaving aside these websites, there is no actual evidence either for or against the existence of these creatures. The lack of evidence against them is inconclusive, while the lack of evidence in favour of them argues against them.
It is impossible to absolutely disprove anything. The only thing that you can do is prove something. There is no proof for the existence of these creatures.
So if you continue to just do nothing other than to say, “where’s the proof?”, then we’ll have to assume that you’re either genuinely neurotic and divorced from reality (and so it’s not worth continuing talking with you, because there’s no way to reach you in your own little world), or else you’re simply pushing your “argument” for the sake of Sony or to be annoying (in which case it’s also not worth continuing to talk to you, because you’re simply a bore).
