I don't think one single thing you have said has flown over my head. I just don't agree wtih you, sorry.
There are some animals that have been labeled a "myth" whose very descriptions etc derived first from people who have claimed to be eyewitnesses, etc. Then, you have animals which are undoubtedly mythological because their origins can be traced back to authors etc who just made them up.
Sometimes what people describe ends up being pretty close to the truth, as in the case of the okapi and sometimes they end up being way off base, such as thinking manatees were half fish/half woman.
My only argument has been in favor of keeping an open mind and allowing scientists to discover new species and explain some of these sightings, if they can. I haven't argued that bigfoot exists, or chupacabra, etc.
And, what makes me less qualified than you or samoth to debate a topic such as this one? I'm not allowed to debate in your opinion because of what? Why is it that anytime I don't agree with you, you think I shouldn't have the right to debate? You didn't point out that anyone else on this thread doesn't deserve the right to debate.
