Meh. Seemed like the second clause was tautological, and didn't merit scrutiny.
Claim(s): It's unlikely that anything exists
[subclaim] unless that thing is immortal
Conclusion: I exist, therefore I am immortal
The immortality element of it seemed to be whatever the technical term is for assuming the conclusion to be true, then using that assumed conclusion as part of the argument for why the conclusion is true. There's a term, but I can't recall it.
Pretty much, you don't have to go beyond the assumption that the likelihood of anything existing is really small. That's not even a good assumption, it's obviously incorrect in a pretty dramatic fashion. Nothing beyond that false assumption bears consideration.
No that's not it. The argument is sound, the falsity of a premise is why it fails. And it isn't so much the "it's unlikely that anything exists" one, which you seem to consider the failure point, but the "unless that thing is immortal" one. Here is an example of a valid argument of that form:
Claim: It's unlikely that any living thing exists
[subclaim] unless the universe supports life
Conclusion: I exist, therefor the universe supports life
The only real problem with Jabba's argument is this assertion: P(E|~H) > P(E|H). Or using the new "I" for immortal rather than "H" for, well who really knows: P(E|I) > P(E|~I). That's it, the rest is mostly either a bunch of back-and-forth philosophizing, the result of Jabba or someone else completely messing up basic math, or just plain ********.
ETA: and there's nothing wrong with the assumption that the likelihood of anything existing is really small. In the space of all models for current theories in physics there's only a relatively small space where, indeed, anything exists. Physical constants have to be set fairly specific or you just get things like the universe immediately collapsing into a black hole or stuff like that.
