I am still confused about the relationship between the two ideas, which makes it hard for me to imagine what the internal contradiction you were wrestling with was. You said that the fact that the evidence is unclear means that the question is irrelevant, but that seems like an odd thing to say since I can imagine lots of questions whose possible answers lack clear evidence, but for which an answer surely exists and is very important -- for example, what happens to my consciousness when I die. So maybe I don't understand what you meant by "irrelevant."
