- So, why wouldn't you accept that your current existence is an appropriate E for P(E\H)?
That's not what you asked. You asked whether a certain premise, if true, would lead to a certain supportable conclusion. Now, as you typically do when you ask a question of that form, you're trying to lay aside the conditional and entrap your critics. I promise you they're not that dumb.
Materialism has no notion of a particular specimen being "set aside." You're trying desperately to paste that notion onto it. And why? Because you've decided on a probabilistic model for your proof, and now you're in a corner because the theory you hope to falsify by it doesn't include your notion -- or any notion -- of any such probabilities or the concepts you're trying to reckon in probability. You don't get to change another person's theory to fit your cobbled-up plan to refute it. That's the definition of a straw-man argument.
In short, we don't accept your proposal because that's not materialism.
As for the rest of it, I covered that already. There is much more than just the formulation of E in your line of reasoning that arrives at P(E|H) being formulated the way you did. And nearly all of it is wrong for reasons that don't relate to E. Even if the E formulation is stipulated (which it isn't) you still don't have a reasonable rationale for P(E|H).
Again, this and many more of your fatal errors were identified
here, a post we know you have read but are now choosing to ignore. Before you demand explanations from people about why they have rejected your claims, you should address the reasons they have already given.
