And above we see the predicted response on how the null hypothesis, developed by a statistician, and used by establishing probabilities based on observation, as outlined in the Wikipedia article, is simply ignored and replaced by some watered down personal "high school" version in order to prop up an argument.
Could you demonstrate that your claim of this limitation of the null hypothesis is not simply an argument form authority built through cherry picking and distortion of the Wikipedia article? The most effective way to do this would be to explain what elements of the null hypothesis cause such a limitation to exist.
We also see continued avoidance of the fact that the word UFO is meant to convey different things in different contexts e.g. in UFO reports or in casual conversation or in an investigative capacity ( historical or otherwise ). Such avoidance ( intentional or otherwise ) only serves to cloud the issue. What are the skeptics really after here? Are we not supposed to be trying to clarify the issue instead?
Similarly, instead of resorting to dodgy appeals to authority with regards to your preferred definition, please present a case for the utility of your definition in the context of honest investigation of the phenomena.
Lastly, we've already established that no sufficient material evidence is readily available that would conclusively prove that UFOs ( alien craft ) have visited planet Earth. So what is the real argument? Is it that it's not reasonable to believe any of the the thousands of unexplained reports? Why is that? Is it just because skeptics like to call everyone else liars or hoaxers or incompetent?
Unexplained means just that. It does not mean insert favorite speculative idea as fact.
