I read at least 10500 solutions have been identified in the 'landscape' hitherto. The observable universe looks most like the loftier peaks in that landscape. As Weinberg notes, the Earth's precise orbit is not derivable from 1st principles yet there must be many earth-like orbits occupied by earth-like planets across the galaxies we see. Similarly, observable universes like ours may (or may not) be the rarest of peaks in a grander scheme, who knows?
