Null Hypothesis = Dull Hypothesis

On our journey through life, most people develop a fairly good sense of prior probabilities and that manifests through excitement. Actual aliens? Exciting. People misinterpreting noisy information? Dull. Telephone game stories getting out of hand? Dull. People lying for clout? Dull. Prestigious people doing all of the above? Dull, dull, dull.

Equal-weighting an arbitrary list of options is a terrible prior distribution that does not tap anyone's knowledge of how the world works. Weighting by excitement, however, does exactly this. To convincingly prove aliens you need to convincingly disprove the dull alternatives. It's easy to imagine extraordinary evidence that could do this -- but I don't see any extraordinary evidence here. I see a bunch of ordinary evidence and people who want to believe.

It’s nonsensical to claim that to prove something you have to disprove alternate explanations. In an information environment where confirmable facts are scarse, you get the clearest vision by operating on probability. And on black-swan-tier questions the ’wisdom of the crowd’ is worthless - too much noise caused by nobody willing to advocate the black swan event, and too little prior events for the crowd to be able to calibrate itself beyond this.
