I'm partial to the idea that we're part of a larger organism. So essentially similar to cell parts but on a different scale. There's something above that, but we are as likely to figure it out as cells are able to figure us out.
What to do with that? I have no idea. In lieu of objective facts, I guess it's useful to pick the good instructions from religions -- usually the ones that they all share are the ones that are worth adhering to. Do to others etc etc.
