This entire field is speculative and nobody argued otherwise. Quite the opposite: I bent over backwards to redundantly state it over and over again. More than I should have, and now I'm beginning to wonder why I bothered if it didn't prevent me from being ignored. The "you can't prove it" objection must be checked at the door for the sake of keeping the speculation interesting. Nobody is arguing that you should walk through the door. It's probably more respectable to refuse, on the whole. Once you walk through the door, though, complaining about proof is a bit silly, like walking into a speakeasy, ordering a drink, and complaining that they have served you illegal alcohol. It's not wrong, but it's also not helpful.
