But of course, we're pretty sure this won't happen. Indeed, let's consider two alternatives:

1. Afterlife exists, but God set it up so that you can't report back because... uh... I'll get back to you?
2. Afterlife doesn't exist, which is why you can't report back (there's nothing to report back from).

In more explicitly Bayesian terms, which is larger: P(~report|afterlife) or P(~report|~afterlife)? Pretty clearly the latter, right? So the lack of reports is therefore evidence against an afterlife. (Maybe not conclusive evidence, but evidence.)
