If one day in the future we developed our understanding of science to the point that we could create a universe with the laws we wanted. That universe needs to be able to support life so we can study it's evolution.
First question: why would we have to do that?
We document all the stages of evolution and learn about the races. Soon one of the animals become intelligent enough for complex communication and their intelligence is increasing. Their morality however is screwed up, they force the weaker ones of the race to become slaves and treat them very badly. They need someone to do the hard work and this is their method.
Second question: if we expect this universe to result in sentient life forms would it be ethical to create it to start with?
We have mastered telepathy so we communicate to the life forms. We feel that we have a moral right to get them to behave more kindly towards other and this is what we do. There are too many beings to communicate to each separately so we only communicate to one. Nobody listens to this one person, instead we use religion to control them. It is the only way forward.
We have now become totalitarian, and it started because of our curiosity. Interesting.
If our religion gets buggered up by them in the future, we could communicate and start again. Of course not every one will be convinced and that would create two competing religions. We need something to motivate them to follow the correct one so we implement the idea of hell and heaven.
Dishonest as well as totalitarian. Even better.
Our idea of morality is no wiser than theirs but since we are advanced and have a lot of history we feel we know better and are therefore superior.
Are we now Gods?
No. Definitely not, although some poor misguided fools would be silly enough to think we were.
