See how you just dismiss ideas because you want to? ''Multiple gods is out because they would have to be acting in such great concert, that they would essentially be one... like one corporation.''
No it's not out. Why would they need to act in a great concert? They would just need to act like humans act when they are building a bridge or a tower. I don't see how that disproves the idea of the possibility of different gods making this universe. All your scientific ''proof'' points out to a complex intelligent creator and that's it. You jump from that to god. I agree that if someone built the universe it had to be someone intelligent enough, obviously but that doesn't mean it's a god. It could just be a being that exists outside of our universe who is just far more advanced than us. We have advanced so much in the last years, imagine where humanity will be in 1000 years or in 1 million years, maybe we will create universes as well.
This is a picture of a rose:
"Rose" in English. Other languages say: roos, Poзa, 玫瑰, rosas, τριαντάφυλλo, Ua tia, and many, many, more.
If the word "God" is too generalized, or too religious-like, or too familiar, or for some other reason unacceptable, we can say: Supreme Being, Great First Cause, Creator, Absolute Being, All Powerful, Prime Mover, World Spirit, or any one of a great number of other word/terms for the powerful being that science shows was the starter of the universe.
For an idea of other ways to say "God," some without the religious connotations that arise in the minds of some people, see:
