I think starting with "why is there something rather than nothing" and arriving at the answer "because there is a god" is a most illogical piece of thinking.
Not because it's wrong. Who's to say it isn't? It's not falsifiable.
But it doesn't provide any more knowledge to believe it.
Same with the "Oooh, the universe has such a complex structure!"
With all the stars and all the planets elsewhere in the universe, it seems likely that there IS an intelligence out there on one or more of them and that it could be greater than humanity.
