Hi Adam.
Yes I can see how you feel, it does marginalize humanity, but the sheer waste of the Anthropic idea, the need for tens or hundreds of millions of universes to come up with the one that has everything just so for life to emerge always seemed wrong. Of course we only have to look around to see how wasteful nature can be (a billion sperm to fertilize one egg for example). And I suspect there is a cosmic aspect to having an observational system (intelligence) within the universe that attempts to know the universe, even though this doesn't necessarily determine the kind of universe we live in.

Regards,
Andrew
