Irrelevant. It wasn't meant to be a perfect analogy, as was already pointed out. It was an example to make a concept obviously clear. Two unknown probabilities do not have to be regarded as equally likely, contrary to the claim that you made in the post that mine was a response to. This is another attempt to nitpick, given that you don't actually have a valid argument, by the look of it.
First of all, if your standard is that your arbitrary Bayesian calculation can only have the binary result of "surprising to you" and "not surprising to you," it's no wonder that you are having such a hard time here with relative probability and keep being unable to demonstrate that the counters to your arguments are wrong. Second, if you really want to go back to your premise, take a serious look back at your OP and what you're actually doing in it. You started from the position that advanced alien life is fairly reasonable on the face of it and then tried to pile on potential issues to try to reduce the supposed likelihood. In short, you only really focused on the negatives. Meanwhile, you glossed over the issues with ESP and only really focused on the positives, going so far as to try to argue that we should ignore things that are normally highly relevant to Bayesian probability calculations, specifically for ESP. The overwhelming difference in treatment rather screams out that the same concept that makes special pleading a fallacy is in play. After all of this, you try to argue that, based on your incredibly biased evaluation, it should be all be thrown out the window and treated evenly.
Simply speaking, you aren't even remotely treating the subject objectively in your premise, which means that your argument as a whole is remarkably untrustworthy, before even getting to anything else.
This, frankly, is nothing more than false assertion. An easy example of why this is blatantly wrong can be found when comparing two similar events for which no direct probability calculation can be performed, with one of them simply having more specific requirements. What is the chance of picking out a blue toy from a pile of toys? What is the chance of picking out a round blue toy that weighs about 3 pounds from the same pile? Indeed, without knowing what the pile contains, the probability will be unknown. However, it is trivially true that the latter chance will never be more likely than the former and will almost always be significantly less likely in practice, which makes the general estimated probability lower than the former. Thus, they cannot be reasonably considered to be equal. In short, your argument fails from the start, before even touching your "going further," because relative probabilities don't have to be directly calculable to be able to be reasonably compared.
I notice that, yet again, you don't even try to objectively consider ESP and advanced alien life while using similar standards and, in fact, didn't address how ESP stands up here at all. In short, at best, you've made half an argument. It's certainly not complete enough to even bother directly addressing, regardless.
