You know Tontar, I think we once had a discussion very similar to this. If you need a refresher about the facts at hand:
http://bigfootforums.com/index.php?/topic/7225-the-ketchum-report/page__st__5380#entry591565
In the end, any discussion that goes on here isn't really about the facts of the situation. It seems to be more about removing intellectual dishonesty. This is the discussion, as I see it.
Skeptics maintain that we have no proof. This is true.
Proponents maintain that the evidence suggests that we are missing something, specifically a 7-10 foot tall bipedal ape. This is true.
Skeptics maintain that you can't say that without proof. This is not true. As far as I know there are no restrictions on the hypothesis chosen in the scientific method, except that it must make sense based upon what has been observed. As far as what has been observed, I make a pretty good accounting of that in the link above, and it seems to me that a 7-10 foot tall bipedal ape is an acceptable guess based on that evidence.
If you believe I am incorrect in saying that 'Bigfoot' is an acceptable hypothesis, please tell me why. And no, "There isn't any proof" or a variation thereof is not an acceptable answer, as stated above.
I'm not sure how they convinced themselves that it made sense to say that we cannot attribute evidence to a conclusion before the conclusion has been proven true. Putting the cart before the horse, don't you think? Without assuming a conclusion, we cannot properly make steps towards proving if that conclusion is actually accurate or not.
If one does not want to consider the possibility of that conclusion being true, then one is not being scientific. Which, in the end, is no problem, as long as you are not trying to make other people believe that you are being scientific. Perhaps you'd be interested in maintaining another hypothesis, maybe that all Bigfoot evidence thus far has either been a hoax or misinterpreted.
If you wish to maintain that hypothesis, you have a lot of work ahead of you and I wish you luck in your endeavor.
Whichever hypothesis or conclusion you support, you cannot avoid the truth of the matter. That this entire Bigfoot issue is, as DWA says, unresolved. Statements to the otherwise are a misrepresentation of the issue, whether purposeful or made out of ignorance.
It would be foolish of me to think that people will see the truth of this post and change the direction of the discussion. Instead of going back and forth about the validity of Bigfoot, something which cannot be proven over an internet forum, they might begin to discuss how better we could go about collecting evidence and, eventually, proof. Then, at least, progress might be made to that eventual goal.
If we keep on like this, the Bigfoot issue is still likely to be unresolved another fifty or sixty years from now.
