Is it possible that Santa Clause really exists, according to you?
I already did. If X is logically possible, then X possibly exists. X could be anything that's logically coherent. ESP and alien life are logically possible. Therefore, they possibly exist.
Physical possibility is another matter, although both ESP and alien life might be physically impossible. If Earth is the only planet where the conditions for life are possible, then alien life is physically impossible.
Is it possible that a fairy rides that black hole and lands on you instead?
E.T.A.: I mean, that this fairy intentionally lands the black hole on you.
I would disagree. It might be considered nit picking though. There is one example of life evolving. That shows that it is at least possible that at least one other time life can evolve.I've made several claims:
Alien life is possible (it might not even exist).
ESP is possible (again, it might not exist)
The probability of alien life existing is the same as the probability of ESP existing. In modal terms, I'm claiming the set of possible worlds that contain alien life is equal to the set of possible worlds where ESP occurs.
Is ESP logically possible according to you? If so, why?
Is it possible that Santa Clause really exists, according to you?
Yes, that is possible. It's possible some god exists that likes fairies and wants to use one to hit you with a black hole. It's possible fairies are messing with our instruments every time we try to observe them.
Getting back to the discussion, both alien life and ESP possibly exist.
Which is more probable? Why?
Is ESP logically possible according to you? If so, why?
Of course, but it's a trivial point. It's possible there are little green elves that disappear as soon as we try to observe them. It's possible that we're boltzmann brains that just popped into existence. It's possible we're in a simulation and the simulator tossed in Santa Claus.
That's why asserting possibility is a weak claim. Anything you can imagine is possible.
But assigning a probability to a claim is much much harder. I can't just say ESP and alien life are equally probable. THAT has to be argued for.

For ESP to be equal in probability, you would need at least one proven case.
Life has 1 data point. ESP has 0 data points. 1 is greater than 0. However, in order to calculate the probability of life elsewhere, you need more than 1 data point. So while the probability is higher, it is unknown and impossible to calculate how much higher.
Imagine a planet being found with only apes on it and scientists saying meh they're just apes, planet is not interesting.

... my claim that ESP and aliens are equally likely. I'll have to think about it.

There was a Star Trek where Kirk and Spock are walking along with tall trees visible in the background and Kirk report "no signs of life".
Yeah, I know what he meant.
What according to you is the difference between "probable" and "likely"?
The burden of proof is on the person claiming X is impossible.
Daylight, is there any evidence that a wandering black hole will intersect the solar system in the next ten years?
Does the complete lack of evidence make such an event possible or impossible?
Hmm....

Alien life would not violate any laws of physics while ESP would, so I would say that alien life is more possible than the entire structure of physics having to be changed.
No. That is, again, the exact opposite of how this actually works.
The burden of proof is on the person making a claim that goes against current understanding. ESP is absolutely against the current understanding of... essentially everything. Biology, chemistry, electromagnetism, quantum field theory. They ALL say it's wrong.
Because ESP isn't logically contradictory. You can claim that it is, but I would like to see the argument for why, for example, reading someone's mind is logically impossible.
