I'm going to guess that there are millions of systems where it didn't work out that way. However, with the sheer numbers of galaxies out there, and the ranges where it could theoretically work, and the billions of such sites, there may indeed be other intelligent life.
If so, I would suspect at some point in their civilization cycle, they too would have considered themselves a unique wonder.
But so they would consider themselves a "unique wonder". How would that limit the influence of God?
