How do you arrive at that conclusion? If we, for example, find out that there's no way a god had anything to do with it, how does that hurt us? Nobody would be able to quote scripture to justify persecution anymore, otherwise they'd be labelled extremists (and likely idiots). The same goes for finding out some sentient being created us, because either they could tell us what's what, or they'd be dead, and thus irrelevant. There's also the possibility that if it was a natural occurrence we could find the what, then the how, then create limitless energy. Or destroy ourselves at the first attempt, but... meh, how would we even notice? I see nothing but good from finding out.
