Your mistake, David, is in considering such issues in isolation. You focus on what we don't properly understand - and my god I never deny there's plenty of that - but you're not looking at the abundance of evidence that life goes on beyond the grave. Whatever the full situation may be, we 'believers' have heard and accepted there are no rules to prevent communication. But we're not here to persuade you of anything and at this point in your life there's maybe no need for you to know. It may be the same for the majority of earth's population. Maybe it's just a mystery and will never be more than ghosts and ghouls and things that go bump in the night I do hope you never have the desperate need to know that some individuals have.
