This is called the Strong Anthropic argument. It is not compelling. Maybe there are lots of universes, and ours happens to be one whose laws allow for life. See Hawkings new book if you want the lowdown about how this argument is faring these days. Maybe there is an intelligent cook who bangs together promising universes. How does that butter my toast? How does that prevent evolution from being a perfectly good explanation for what I can see around me? How does that demonstrate that I should consider such a creature a benevolent and trustworthy object of my adoration? How does it answer any useful question whatsoever?
