IF the estimated probability that it is more likely than UNlikely that alien life lives out there somewhere is VALID because there IS life out there then that estimated probability would IOW equate to evidence. And that itself would be a rational belief and evidence-based.
If the estimated probability that it is more likely than UNlikely that alien life lives out there somewhere is INvalid because there ISN'T life out there then that estimated probability would NOT equate to evidence because it would be incorrect because there ISN'T life out there. So the reasoning, the estimated probability would be irrational because it would be INvalid and it would not equate to evidence so it would be faith-based.
So that itself would be an IRrational belief and faith-based - IOW you would be believing 'on faith'.
It is rational to believe in something with evidence. It is NOT rational to believe WITHOUT it - hence the term 'rational faith' is an oxymoron.
